Conversion of starch to organic acid is essential for

Options

A. Stomatal closure
B. Stomatal opening
C. Stomatal initiation
D. Stomatal growth

Answer

B

Explanation

With the opening of stomata hydrogen ions which are present in the guard cells are pumped out of the guard cells resulting in the lowering of positive charge and accumulation of negative charge in the guard cells. As result potassium ions enter the guard cells. Due to this osmotic pressure in the guard cells is lowered which attract the water to enter into the cell as a result starch in the chloroplast is converted into malate ions.
