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.
Plants are made up of two organ systems: the shoot system and the root system. For terrestrial plants the shoot system is above ground and consists of a number of organs. These include stems, leaves, and flowers.lants are autotrophic, meaning that they produce their own food (via photosynthesis), and as a result ultimately produce food for the ecosystem's consumers (such as humans). Understanding plant function is the key to enhancing crop production, preserving plant biodiversity, producing medicines, and much more.
