Question

Zone of maximum water absorption in root?

• A. Mature zone
• B. Zone of differentiation
• C. Root cap
• D. Cell elongation zone

Answer 1

The correct option is A Mature zone

The zone of rapid water absorption usually lies some 20 – 200mm from the root tip behind the meristem, where the xylem is not fully mature and the epiblema as well as the endodermis are still permeable.This area is usually characterized by the presence of root hairs which serve to increase the area of contact between the root surface and soil. The root hairs develop mainly at the tip just above the zone of elongation (cell maturation) i.e., the mature zone.

So, the correct option is 'Mature zone'.
