MCQ
Growth is maximum in the zone of:
- ACell division
- BCell elongation
- CCell maturation
- DAll of the above
✓
Answer
- Cell elongation
Explanation:
Growth is estimated by an increase in cell number, area, volume, and length.Cell growth undergoes three major phases.They are as followed:
a) During cell division, the meristematic cells divide rapidly to increase the number of cells.This increases the number of cells.
b) During the cell elongation phase, the newly formed cells elongate and increase in length and volume.It also shows increased vacuole formation and new cell wall deposition. Amount of protoplasm increases.
c) During cell differentiation, the cell has achieved maximum growth and proceeds towards maturation to attain specific function.
As, maximum increase in length and volume takes place in the cell elongation phase. It is considered as zone of maximum growth.
