The primary function of plant roots is absorption of water and minerals from the soil. Most of plant roots anchor the plant in place. In some cases aerial roots help plants to absorb water from the air (in case of many species of Ficus) and also help in climbing (as in case of Smilax).he roots anchor the plant in place and prevent it from moving, being blown over or washed away by water. Absorption of water and dissolved nutrients from the soil. Root hairs increase the surface area of the roots system as a whole and enable it to absorb large amounts of water from the soil. Absorption of oxygen.
In the leaves of a plant is a substance called chlorophyll. Chlorophyll makes leaves green. It also traps the energy from the sun so the plant can use it. When plants take carbon dioxide from the air, they release oxygen. Animals use this oxygen to grow. We release carbon dioxide, which the plants use. Plants also need minerals from the soil to grow. Nitrogen helps them grow and make leaves. Phosphorus helps grow strong roots. Potassium helps the plant make fruit and it keeps them healthy. Plants need large amounts of nitrogen, phosphorus and potassium. The soil doesnât always have enough of these nutrients. Gardeners use fertilizer to give plants more nutrients. Fertilizers are sort of like vitamins for plants.
