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.
The Leaf. Two Functions of the Leaf. 1  Photosynthesis is the process when leaf cells containing chlorophyll take in carbon dioxide and water and using sunlight, make sugar and oxygen. 2  Transpiration is the loss of water from the leaf.3  This helps to draw water up through the plant from the roots. The female part of the flower is the pistil (composed of the stigma, the thin style and the ovary). 2  Pollination occurs when pollen is transferred by insects or wind from the anther to the stigma. 3  Chemicals called enzymes 'drill' a channel down through the style to the ovary where the egg is.
