Question

Write a note on the morphological structure of the root.

Answer 1

A typical root of terrestrial plants has four regions from the apex to the base of the root. These are:

1. Region of cell division: This is a meristematic region which lies at the tip of the root, where the division of cell occurs.
2. Region of cell elongation: Cells of this region undergo elongation, as a result, the length of the root increases.
3. Region of absorption: This is the region for water absorption and bears root hairs. Root hairs absorb water and mineral salts from the soil. iv. Region of maturation: Cells of this region undergo maturation and form different types of tissues.
