Q. Lateral roots in higher plants arise from

NTA AbhyasNTA Abhyas 2020Morphology of Flowering Plants

Solution:

The lateral roots arise from the cells of pericycle and hence, the root branches are said to be endogenous in origin (arising from a layer inner to endodermis). The lateral roots help in absorption of water and mineral salts from the soil. The meristematic cells of the lateral root push through the endodermis and cortex and then pierce through the epidermis to come out to form the lateral root.
