Guard cells control the massive amounts of gaseous exchange that takes place through the small pores known as stomata. Thus, the correct option for this question is C.
What are Guard cells?
Guard cells may be defined as the kidney-shaped cells that envelop the stomata and are responsible for opening and closing of the stomatal pore.
A large amount of water is lost as a result of the opening of stomata for a long time, so the plant closes these pores when they do not need carbon dioxide for photosynthesis.
The guard cells swell when water flows into them, causing the stomatal pore to open, while the guard cell shrinks when water flows away from them, causing the stomatal pore to close.
Therefore, Guard cells control the massive amounts of gaseous exchange that takes place through the small pores known as stomata. Thus, the correct option for this question is C.
