Question

Root hairs occur in the zone of

• A. Cell division
• B. Cell elongation
• C. Cell maturation
• D. Mature cells

Answer 1

The correct option is C Cell maturation

Root consist of four parts:-

1. Root cap which protects the root and secrete mucilage which lubricates the root.
   
2. Region of meristematic activity where apical meristem is present and increase the length of root.
3. Region of elongation where the newly-formed cells increase in length, thereby lengthening the root.
4. Region of maturation that bears unicellular root hairs which increases the surface area and helps in the absorption of water.

So, the correct option is 'Cell maturation'.
