Answer» Meaning of Root:Generally, root is said to be the part of a plant which remains inside the soil. But there are subaerial as well as aerial ROOTS also. Actually, root is a positively geotropic part of the plant having a root cap and many unicellular root hairs. Ontogenically the root arises from the radicle.(i) Tap root:The primary root with its many small lateral branches, which are normally meant to absorb the water from the tap root SYSTEM.(ii) Adventitious root:A root that grows from any part of the plant like STEM, leaves etc. but not from the radicle, is CALLED adventitious root. |
