Question

Glycolate induced opening of stomata, takes place due to

• A. Presence of Oxygen
• B. Low CO${}_2$ concentration
• C. High CO${}_2$ concentration
• D. Absence of CO${}_2$

Answer 1

The correct option is B Low CO${}_2$ concentration

According to glycolate induced stomatal opening, light causes photosynthesis, which lead to reduction in CO${}_2$ concentration synthesis of glycolate, oxidation of glycolate ATP synthesis, activation of K${}^{+}$ pump, movement of K${}^{+}$ in guard cell movement of water into guard cells, swelling of guard cell opening of stomata.

So, the correct answer is option B.
