Vedclass · Answer

(A) The opening and closing of stomata are primarily regulated by the concentration of $K^{+}$ ions in guard cells,the conversion of starch to sugar (and vice versa),and environmental factors like light and $CO_{2}$ concentration.$N_{2}$ (nitrogen) is an inert gas present in the atmosphere. While it is essential for biological nitrogen fixation by specific bacteria,it does not play a direct role in the physiological mechanism of stomatal movement.Therefore,the opening of stomata is not affected by $N_{2}$.
