NEET BIOLOGY

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

Detailed explanation-2: -The zone of elongation is where the newly formed cells increase in length, thereby lengthening the root. Beginning at the first root hair is the zone of cell maturation where the root cells begin to differentiate into special cell types.

Detailed explanation-3: -ZONE OF MATURATION (= ZONE OF CELL DIFFERENTIATION): The vascular tissues of the root become differentiated. Instead of forming bundles containing xylem and phloem, as in leaves and young shoots, the xylem forms a solid mass in the center, surrounded by strands of phloem.

Detailed explanation-4: -The elongation zone contains cells that do not divide and instead elongate rapidly, about 10 times faster than meristem cells. Finally, shootward of the elongation zone comes the maturation zone, where cells neither elongate nor divide but take on their mature functions.

Detailed explanation-5: -The zone of cell division is closest to the root tip and is made up of the actively-dividing cells of the root meristem, which contains the undifferentiated cells of the germinating plant. The zone of elongation is where the newly-formed cells increase in length, thereby lengthening the root.
