DENDROLOGY

Detailed explanation-1: -So, the correct answer is ‘Maturation zone-Elongation zone-Cell division zone’

Detailed explanation-2: -If we look at a root tip, we can recognize four root regions: the root cap, the region of cell division, the region of elongation and the region of maturation (Figure 2.2. 1).

Detailed explanation-3: -Final answer: The region of elongation is responsible for the growth of the root in length.

Detailed explanation-4: -The maturation zone lies at the tip region, then comes the elongation region where cells elongate, the meristematic zone gives rise to primary tissues, and at the end comes the root cap, which provides protection to fragile root hairs.
