What do we need to grow?
Animals and humans grow and change as they get older. Animals and humans need water, food and air to survive. Food can be sorted into different food groups. Exercise helps us to keep healthy.
What two things do plants make that we need to survive?
Plants provide us with food, fiber, shelter, medicine, and fuel. The basic food for all organisms is produced by green plants. In the process of food production, oxygen is released. This oxygen, which we obtain from the air we breathe, is essential to life.
The only source of food and oxygen are plants; no animal alone can supply these. Shelter, in the form of wood for houses; and clothing, in the form of cotton fibers, are obvious uses of plant materials. But we must not forget fuel, furniture, paper products, certain medicines like aspirin, and many other products like perfume and chewing gum.
To these tangible aspects of the plant world we must also add the importance of beauty and relaxation derived from plants. Since animals are surrounded by and dependent upon plants, the factors that influence plant growth, structure, and distribution, affect the animal world as well.
How do plants live and grow?
Plant growth and development Photosynthesis, respiration and transpiration are the three major functions that drive plant growth and development (Figure 24). All three are essential to a plant’s survival. How well a plant is able to regulate these functions greatly affects its ability to compete and reproduce.
Which thing helps us to grow?
Key Takeaways –
Proper nutrition and a healthy lifestyle are two important factors for increasing height. Poultry, green leafy vegetables, and dairy have essential nutrients such as proteins and vitamins that might help in growing taller. Consuming sugar may lead to obesity and diabetes, and adversely affect the body’s potential growth. Proper posture and optimum sleep might help increase height. Incorporate exercise into the daily routine.

How do plants live and survive?
Photosynthesis and Plant Respiration – Plants depend on the cycle of photosynthesis and respiration for their survival.
- Photosynthesis is the process used by plants, algae and a few bacteria to turn sunlight, carbon dioxide, and water into food and oxygen.
- Humans and animals inhale the oxygen produced by plants.
- Respiration is the process of releasing energy from food.
- Animals take in the oxygen produced by plants, transport it to the cells, and use it to release food. Carbon dioxide is released from the body in the process.
- Plants absorb this carbon dioxide to provide the energy they need for growth and development. This is the never-ending cycle that helps to sustain life on earth.
What causes a plant to grow?
When planting a flower bed or a vegetable garden it is important to understand what plants need to grow. There are 4 main factors that can affect the growth of your plants. They are water, light, nutrients, and temperature. These four things affect the growth hormones of the plant, which will either make the plant grow quickly or slowly. It is important to learn as much as you can about these four factors so that you can plant your garden accordingly to achieve a lush and healthy garden. Water, light, temperature, and nutrients are the 4 things that affect the growth of a plant the most. Plants have evolved throughout time in different locations throughout the world. Some plants developed in tropical locations under the canopy of large trees while others developed on slopes of harsh mountain ranges. For this reason, plants have adapted to different types of light. From season to season light varies in intensity. In the winter the days are much shorter and therefore there is less light. During the spring the amount of light that is available starts to increase as does the intensity. The light and the temperature changes that come in the spring will stimulate plants to break dormancy and start to grow new leaves.
- Sunlight that is available during the summer months will encourage fruiting and flowering.
- During the fall months when the light starts to change again, many plants will begin shedding their leaves.
- When purchasing plants it is important to make sure that you have an area in mind to plant them so that they get the amount of sunlight that they require each day.
Each species has its own specific light requirements. The popular Alocasia Black Velvet, for instance, needs moderate indirect light, whereas a jade plant will want bright light at least 6 hours a day. In order to survive, plants have to have water. Most plants are made up of nearly 90 percent water. Without the appropriate amounts of water, plants will be stressed and eventually die. Even plants that live in the desert such as the cactus need water, they just need less of it than other types of plants. Humidity and water in the air can help encourage plant growth. However, providing too much water can also cause plants to die. It is important that you look up information about how much water your plants need and be sure to provide them with this amount in order to promote healthy growth. Weather or temperature plays an important role in plant growth. Plants will slow down or speed up their growth rate based on the temperature. Warm temperatures encourage growth and germination. A warmer temperature will actually trigger a chemical reaction inside the cells of a plant and this will speed up respiration, transpiration, and the photosynthesis process.
Plant growth is faster during warmer periods and will slow down or become dormant in a cooler period. There are certain nutrients that plants need in order to grow. Carbon, oxygen, and hydrogen are three of the nutrients that plants need. They get these from water and from air. The other nutrients that the plant needs are found in the soil.
If a plant lacks any nutrient, plant growth can be stunted. There are 2 categories of soil nutrients needed to improve plant growth, micronutrients and macronutrients. Plants need more macronutrients than micronutrients. The macronutrients that plants need include: Micronutrients that plants need include iron, copper, as well as several other elements.
Why do plants need light?
Quick facts –
Sufficient light is important to growing healthy plants. Select a plant with requirements that match the light environment in your home or office. Supplemental lighting can make up for a lack of natural sunlight. There are many types of artificial lights in different styles and sizes to fit your needs and budget.
Light is one of the most important factors for growing houseplants. All plants require light for photosynthesis, the process within a plant that converts light, oxygen and water into carbohydrates (energy). Plants require this energy in order to grow, bloom and produce seed. Without adequate light, carbohydrates cannot be manufactured, the energy reserves are depleted and plants die.
What nutrient do plants need?
Plant nutrients in the soil Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.
What age do boys stop growing?
Changes in Boys – Boys tend to show the first physical changes of puberty between the ages of 10 and 16. They tend to grow most quickly between ages 12 and 15. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop. Other features of puberty in boys include:
The penis and testicles increase in size. Pubic hair appears, followed by underarm and facial hair. The voice deepens and may sometimes crack or break. The Adam’s apple, or larynx cartilage, gets bigger. Testicles begin to produce sperm.
How does food help us to grow?
Foods and nutrients –
|Foods provide nutrients so we can grow and be active and healthy|
A food is something that provides nutrients. Nutrients are substances that provide:
energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy.
There are many different nutrients.We divide them into: Macro (big) nutrients that we need in large amounts. These are:
carbohydrates (starches, sugars and dietary fibre); fats – there are several kinds (see Box 4); proteins – there are hundreds of different proteins.
Micro (small) nutrients that we need in small amounts. There are many of these but the ones most likely to be lacking in the diet are:
minerals – iron (see Box 6, page 19), iodine and zinc; vitamins – vitamin A, B-group vitamins (including folate) and vitamin C.
BOX 4 · FATS, FATTY ACIDS AND CHOLESTEROL
| Fats and oils provide a concentrated source of energy and the essential fatty acids needed for growth and health. They aid the absorption of some vitamins such as vitamin A and improve the taste of meals. Some fatty/oily foods contain important vitamins. Fats and oils contain different ‘fat-nutrients’. These include unsaturated fatty acids, saturated fatty acids, trans fatty acids and cholesterol. Unsaturated fatty acids Two of the unsaturated fatty acids are called ‘essential fatty acids’ because the body cannot make them. They are needed for building cells, especially the cells of the brain and nervous system. Unsaturated fatty acids contain a group called ‘omega-3 fatty acids’, which help to protect the body from heart disease.
Examples of foods containing mainly unsaturated fatty acids are most vegetable oils, groundnuts, soybeans, sunflower seeds, sesame seeds and other oilseeds, oily fishes and avocados. Foods rich in omega-3 fatty acids are oily sea fish and some seeds and pulses such as linseed and soybeans.
Saturated fatty acids
Examples of foods containing mainly saturated fatty acids are butter, ghee, lard/cooking fat, whole milk, cheese, fats from meats and meat products (e.g. sausages) and poultry, red palm oil and coconuts.
Trans fatty acids When vegetable oils are processed to make them harder (e.g. for use in margarine and other solid fats), some of the unsaturated fatty acids are changed into trans fatty acids. These behave like saturated fatty acids. We should eat as little of the foods containing trans fatty acids as possible.
Examples of foods containing trans fatty acids are margarine and lard (shortening), fried foods, such as chips (French fries) and others, commercially fried foods, such as doughnuts, as well as baked goods, biscuits, cakes and ice creams.
Cholesterol Cholesterol is found only in animal foods but the body can make it from other fatnutrients. We need some cholesterol for our bodies to grow and function properly. There are two kinds of cholesterol in the blood.
High levels of ‘good’ cholesterol (high-density lipoprotein) seem to reduce the risk of heart disease. Eating foods containing mainly unsaturated fatty acids tends to increase the level of good cholesterol. High levels of ‘bad’ cholesterol (low-density lipoprotein) seem to increase the risk of heart disease. Eating foods containing mainly saturated fats tends to increase the level of bad cholesterol.
Fat needs Fat needs are expressed as ‘percent of total energy needs’ (see Appendix 2). The percent of total energy that should come from fat in a healthy balanced diet is:
30-40 percent for children on complementary feeding and up to the age of two years; 15-30 percent for older children and most adults; for active adults up to 35 percent is acceptable; At least 20 percent up to 30 percent for women of reproductive age (15-45 years).
This means the diet of a woman of reproductive age who needs approximately 2 400 kcal/day should contain about 480-720 kcal from fat or oil. This is equivalent to 53-80 g of pure oil (or about 11-16 level teaspoons). Part of the fat in a diet is not added in the kitchen at home but is ‘hidden’ in foods such as meat, milk, groundnuts and oilseeds as well as fried foods. Fat and health It is recommended that less than one-third of the fat in the diet is in the form of saturated fatty acids. Red palm oil and coconuts/coconut oil are foods rich in saturated fatty acids but, unlike other such foods, they do not seem to increase the risk of coronary heart disease. Moderate intake of coconut, for instance, seems to be acceptable, providing other foods high in saturated fats are eaten as little as possible. This is particularly true where the overall lifestyle lessens the risk of heart disease. Such a lifestyle could, for example, be one with a high physical activity level, high intake of fish, vegetables and root crops, low intake of salt and little or no use of tobacco or alcohol. Red palm oil is also a good source of other important nutrients, such as vitamin A and vitamin E. Ideally trans fatty acids should provide less than 1 percent of the total energy intake (or not more than 2 g for most adults). For many families this means they should, when possible, eat more of the foods rich in unsaturated fatty acids (e.g. foods from plants and oily sea fish), less of the foods high in saturated fatty acids, and much less of the foods high in trans fatty acids.
Our bodies use different nutrients in different ways as shown in Box 5. BOX 5 · IMPORTANT USES OF SOME NUTRIENTS
|Nutrient||Main use in the body|
|Carbohydrates – starches and sugars||To provide energy needed to keep the body breathing and alive, for movement and warmth, and for growth and repair of tissues. Some starch and sugar is changed to body fat.|
|Carbohydrates – dietary fibre||Fibre makes faeces soft and bulky and absorbs harmful chemicals, and so helps to keep the gut healthy. It slows digestion and absorption of nutrients in meals, and helps to prevent obesity.|
|Fats||To provide a concentrated source of energy and the fatty acids needed for growth and health. Fat aids the absorp-tion of some vitamins such as vitamin A.|
|Proteins||To build cells, body fluids, antibodies and other parts of the immune system. Sometimes proteins are used for energy.|
|Water||To make fluids such as tears, sweat and urine, and to allow chemical processes to happen in the body.|
|Iron||To make haemoglobin, the protein in red blood cells that carries oxygen to the tissues. To allow the muscles and brain to work properly.|
|Iodine||To make thyroid hormones that help to control the way the body works. Iodine is essential for the development of the brain and nervous system in the foetus.|
|Zinc||For growth and normal development, for reproduction and to keep the immune system working properly.|
|Vitamin A||To prevent infection and to keep the immune system working properly. To keep the skin, eyes and lining of the gut and lungs healthy. To see in dim light.|
|B-group vitamins||To help the body use macronutrients for energy and other purposes. To help the nervous system to work properly.|
|Folate||To make healthy red blood cells and to prevent abnormalities in the foetus.|
|Vitamin C||To aid the absorption of some forms of iron (see Box 6). To destroy harmful molecules (free radicals) in the body. To help wound healing.|
BOX 6 · IRON ABSORPTION
| Iron from meat, liver and other offal, poultry, fish and breastmilk is well absorbed in the gut. Iron from other milks, eggs and all plant foods is poorly absorbed, but other foods in the same meal affect the absorption of this type of iron.
Meat, fish and vitamin C-rich foods (fresh fruits and vegetables) increase the absorption of this type of iron so more is absorbed. Some foods, such as tea, coffee and wholegrain cereals, contain ‘antinutrients’ (e.g. phytate) that decrease the absorption of this type of iron.
The best way to make sure that we get enough of each nutrient and enough energy is to eat a mixture of foods. Topic 3 explains how to combine foods to make good meals. Appendix 1 lists sources of each nutrient (see Tables 1 and 3) and the nutrient content of different foods (see Table 2).
What is plant survival?
Keep your plants healthier by understanding their needs – To understand what goes into the perfect potting mix, it’s helpful to appreciate how plants thrive. Plants have four basic survival needs: water, air, food, and soil structure that shelters roots.
|1. Water: Roots pull water from the space between particles. If the mix is too dry, they can’t pull hard enough; if it’s too wet and waterlogged, they can’t function. To complicate things, container mixes can collapse under the weight of water that doesn’t drain, yet they also dry out more quickly than native soil. Water-holding and water-draining ingredients balance these demands in the potting mix.|
|2. Air: Living roots need oxygen and plentiful space to grow. For this, potting mixes need an ingredient that will fluff and lighten, allowing water to drain and roots to breathe.|
|3. Food: Organisms and organic matter in soil retain nutrients and feed plants. Plant nutrients in container gardens, on the other hand, are added artificially. In a potting mix, these nutrients are supplied by organic materials, along with organic or chemical fertilizers.|
|4. Structure: Materials that add structure in potting mixes help to anchor roots and shelter them from harsh conditions. These ingredients also prevent compaction and add weight to keep containers from toppling over|

Why is water important to plants?
Water is an essential nutrient for plants and comprises up to 9 5% of a plant’s tissue. It is required for a seed to sprout, and as the plant grows, water carries nutrients throughout the plant. Water is responsible for several important functions within plant tissues.
Water is necessary for photosynthesis, which is how plants use energy from the sun to create their own food. During this process, plants use carbon dioxide from the air and hydrogen from the water absorbed through their roots and release oxygen as a byproduct. This exchange occurs through pore-like stoma on the leaves.
Water is evaporated on the leaves, as well, in a process called transpiration, which keeps plants from overheating. Warm temperatures, wind and dry air increase the rate of transpiration. As water evaporates through the leaves, more water is pulled up through the roots of the plant.
Nutrients and sugars from photosynthesis are dissolved in water and move from areas of high concentration, like the roots, to areas of lower concentration, such as the blooms, stem and leaves, for growth and reproduction. Water is responsible for cell structural support in many plants, creating a constant pressure on cell walls called turgor, which makes the plant flexible yet strong and allows it to bend in the wind or move leaves toward the sun to maximize photosynthesis.
Low moisture will cause browning of plant tissues and leaf curling, eventually leading to plant death. When watering garden plants, it’s important to provide a thorough, deep watering rather than frequent, light watering to encourage deeper root growth.
How Plants Take Up Water
By Jodi Richmond, WVU Extension Service Agent – Mercer County
Do plants need energy to survive?
Plants don’t move around, so why do they need energy? Answer Verified Hint: Photosynthesis requires energy, which is provided by sunlight. Carbon dioxide and water are transformed into oxygen (a waste product that is released back into the atmosphere) and glucose throughout this process (the source of energy for the plant).
Complete answer: Note:-
Why do plants require energy even if they do not move? Plants may generate their own energy. Plants require water and sunlight to produce their own food energy, which is known as: (Photosynthesis).Because they are living entities, they require energy.
- Energy is required for a variety of processes in living things, including growth and reproduction.
- As a result, energy is extremely vital.Plants do not require transportation from one location to another.
- Plants’ movements are usually at the molecular level, therefore they require significantly less energy than animals.
Animals, on the other hand, must migrate from one location to the next in order to get food. Animals, on the other hand, have a much higher energy requirement than plants.Energy feeds your body’s internal functions, repairs, builds, and maintains cells and body tissues, and helps you engage with the physical environment through external activities.
Water, the most crucial nutrient in your body, aids in the chemical activities that generate energy from food.The body requires energy to stay alive, grow, stay warm, and move about. Food and drink are sources of energy. It is derived from the diet’s fat, carbohydrate, protein, and alcohol content.Plants use the sun’s energy to convert water and carbon dioxide into glucose, a sugar.
Plants use glucose for energy and to manufacture cellulose and starch, among other things. Cell walls are made up of cellulose. As a food source, starch is kept in seeds and other plant parts.Photosynthesis is the process by which plants produce food. Plants use their leaves to trap light energy during photosynthesis.
What do plants breathe?
Gases enter leaves through thousands of tiny pores called stomata (sing. stoma). In most plants these are found on the underside of leaves, where they’re hidden from strong sunlight and protected from dust. As well as allowing gases in and out, stomata also control water loss. When roots detect the soil is dry, they send a chemical signal to the leaves that causes specialised cells, called guard cells, to close the pores, stopping water vapour from escaping (transpiration). When stomata close, gas exchange is also reduced. Prolonged closure can adversely affect how well a plant can photosynthesise, respire and grow. To prevent stomata closing unnecessarily, add organic matter to the soil before planting so it holds more water, mulch beds to reduce moisture loss and pay close attention to watering during dry spells. In daylight, plants are both respiring and photosynthesising, so oxygen and carbon dioxide are diffusing in and out of the leaves. But overnight, without sunlight, photosynthesis stops and stomata close. With just respiration taking place, only oxygen diffuses into the leaves and only carbon dioxide diffuses out.
What are the 5 basic needs of plants?
The vital needs of a plant are very much like our own—light, water, air, nutrients, and a proper temperature. The relative importance of each of these needs differs widely among plants. The ability of a plant species to spread throughout a geographic area is a direct result of its adaption to the abiotic and biotic components of the area.
- Although most habitat components act on a plant simultaneously and should be considered together, the lack of one essential component can determine the health of a plant.
- This factor, whatever it may be, is referred to as a limiting factor.
- The concept of limiting factors applies to all aspects of a plant’s interaction with its habitat.
Any factor in the ecosystem can act as a limiting factor. For example, water is important to many species; most species cannot live in desert regions because of lack of water and most cannot live in marshes because of excess water. Extreme temperatures inhibit plant growth in many regions; lack of warmth in winter is a limiting factor that keeps many species restricted to the tropics.
How do we grow?
How body tissues grow – Body tissues grow by increasing the number of cells that make them up. Cells in many tissues in the body divide and grow very quickly until we become adults. When we are adults many cells mature and become specialised for their particular job in the body.
- So they don’t make copies of themselves (reproduce) so often.
- But some cells, such as skin cells or blood cells are dividing all the time.
- When cells become damaged or die the body makes new cells to replace them.
- This process is called cell division.
- One cell doubles by dividing into two.
- Two cells become four and so on.
The diagram below shows cells dividing. It seems that human cells can reproduce up to 50 or 60 times at most. Then they usually die.
Why do we need to grow in life?
The benefits of personal growth – Despite the discomfort and pain that the pursuit of personal growth can cause – there is a reason people are doing it. Theodore Roosevelt said it well: “Nothing in the world is worth having or worth doing unless it means effort, pain, difficultyI have never in my life envied a human being who led an easy life.
Learning to better control your emotions and negative thoughts Overcoming procrastination or laziness Being open to learning new things and skills – having a ‘growth mindset’ Finding peace and contentment with things you cannot change Better work and relationship outcomes Making better progress on your personal goals A sense of personal pride, achievement and hope
What is needed for a child to grow?
How Can Parents Help? – You can do a few things to help your child grow and develop normally. For their overall health and wellness, kids need:
Enough rest: Sleep patterns vary by age and individual child. But most kids need an average of 10 to 12 hours of sleep per night. Sleep gives growing bodies the rest they need to grow well. Good nutrition: A balanced diet full of essential vitamins and minerals will help kids reach their full growth potential. Regular exercise: Because obesity is a problem for many kids, parents should make sure that their kids exercise regularly. Bicycling, hiking, in-line skating, sports, or any enjoyable activity that will motivate kids to get moving will promote good health and fitness and help them maintain a healthy weight.
