Which of the following facilitates opening of stomatal aperture ?
Updated On: Jul 11, 2024
- Decrease in turgidity of guard cells
- Radial orientation of cellulose microfibrils in the cell wall of guard cells
- Longitudinal orientation of cellulose microfibrils in the cell wall of guard cells
- Contraction of outer wall of guard cells
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Cellulose microfibrils are oriented radially rather than longitudinally which makes easy for the stoma to
open.
