What is the benefit of the \(\mathrm{C} 4\) adaptation?
1 Photorespiration occurs
2 Stomata close during day
3 Minimizes water loss

Which of the following facilitates the 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 microfibrils in the cell wall of guard cells
4 Contraction of outer wall of guard cells
Explanation:
Radial orientation of cellulose microfibrils makes easy for the stoma to open.
