Answers
Plants require many things to grow:-
WATER and NUTRIENTS - Most all plants use water to carry moisture and nutrition between roots and soil. Water as well as nutrients is normally taken up through the roots from the soil.
AIR and SOIL -Fresh ,clean air and healthy soil is very important for the growth of plants.Healthy air is very vital for plants as harmful air can limit their ability to take carbon dioxide.
LIGHT and TEMPERATURE - Plants also need sunlight to grow .Light is used as energy for making food also known as photosynthesis.Temperature is also important as most plants prefer cooler nighttime temperature and warm daytime temperatures.
SPACE and TIME- Space is yet another factor to consider growing plants.Both roots and foliage(leaves) need room to grow .Finally, plants require time to grow.
They do not grow overnight .Most plants require a particular number of days, months or years to grow.
hope it helps ...✌✌
Plants are everywhere around us, but how do plants grow and what makes plants grow? There are many things plants need to grow such as water, nutrients, air, water, light, temperature, space, and time.
Water & Nutrients
Like humans and animals, plants need both water and nutrients (food) to survive. Most all plants use water to carry moisture and nutrients back and forth between the roots and leaves. Water, as well as nutrients, is normally taken up through the roots from the soil. This is why it’s important to water plants when the soil becomes dry.
Fertilizer also provides plants with nutrients and is usually given to plants when watering. The most important nutrients for plants growing needs are nitrogen (N), phosphorus (P), and potassium (K). Nitrogen is necessary for making green leaves, phosphorus is needed for making big flowers and strong roots, and potassium helps the plants fight off disease.
Too little or too much water or nutrients can also be harmful.
Air & Soil
What helps plants grow besides water and nutrients? Fresh, clean air and healthy soil. Dirty air caused by smoke, gases, and other pollutants can be harmful to plants, limiting their ability to take in carbon dioxide from the air for making food (photosynthesis). It can also block out sunlight, which is also necessary for healthy plant growth.
Healthy soil is extremely vital to plants. In addition to essential nutrients found in soil (from organic matter and micro-organisms), soil provides an anchor for plant roots and helps support the plants.
Light & Temperature
Plants also need sunlight to grow. Light is used as energy for making food, a process called photosynthesis. Too little light can make plants weak and leggy looking. They will also have fewer flowers and fruits.
Temperature is important too. Most plants prefer cooler nighttime temps and warmer daytime temperatures. Too hot and they may burn, too cold and they will freeze.
Space & Time
Space is yet another factor to consider when growing plants. Both the roots and foliage (leaves) need room to grow. Without enough room, plants can become stunted or too small. Overcrowded plants are also more likely to suffer from diseases since airflow may be limited.
Finally, plants require time. They do not grow overnight. It takes time and patience to grow plants, some more so than others. Most plants require a particular number of days, months, or even years to produce flowers and fruit.
