Give a short note on sucking/ haustorial/ parasitic roots with diagram

Answer 1

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.
