General purpose of this lecture is to present on support and transport in plants. Here briefly describe on two types of root systems- tap root system and adventitious root system. Here also present functions of the roots. Root cap is made up of parenchyma cells. It protects the inner layers of the root. The growing point is made up of meristematic cells. Some of the new cells produced replace the parenchyma cells of the root cap which were damaged. The root hair region has root hairs, which absorb water and mineral salts.
