Correct option: (2) Radial orientation of cellulose microfibrils in the cell wall of guard cells
Explanation:
Cellulose micro fibrils are oriented radially rather than longitudinally which makes easy for the stoma to open.
Which of the following facilitates opening of stomatal aperture? (1) Decrease in turgidity of guard cells (2) Radial orientation of cellulose microfibrils in the cell wall of guard cells (3) Longitudinal orientation of cellulose micro fibrils in the cell wall of guard cells (4) Contraction of outer wall of guard cells
