NEET Solved Paper 2017 Question 74
Question: Which of the following facilitates opening of stomatal aperture?
Options:
A) Longitudinal orientation of cellulose micro fibrils in the cell wall of guard cells
B) Contraction of outer wall of guard cells
C) Decrease in turgidity of guard cells
D) Radial orientation of cellulose micro fibrils in the cell wall of guard cells
Show Answer
Answer:
Correct Answer: D
Solution:
- The radial orientation of cellulose microfibrils in the cell walls of guard cells facilitates the opening of the stomatal aperture. This orientation allows the guard cells to expand and curve outward when they become turgid, thereby opening the stomata.
