When stomata open the pH of the guard cell increases.
Option: (a)
Explanation:
- The opening and closing of the stomata depend on the amount of carbon dioxide which is present in the dissolved form in water.
- When carbon dioxide is dissolved in water carbonic acid is produced. The more the amount of carbonic acid the more is the acidity and hence lesser is the pH of the medium.
- The pH of guard cell increases when the stomata opens because you 2 opening of the stomata, carbon dioxide is lost and the pH is increased due to alkalinity.
