The opening and closing of the stomatal pores depends upon:(a) oxygen (b) water in guard cells (c) temperature (d) concentration of CO₂ in stomata

Academic Biology NCERT Class 10

Correct Answer: (b) Water in guard cells.

Explanation: The guard cells swell up or become turgid when water flows into them, causing the stomatal pores to open. Similarly, the pore closes if the guard cells shrink or become flaccid by losing water.
