what is responsible for the opening and closing of the stomata?
A
sunlight
B
guard cell
C
turgor pressure
D
roots
Explanation: 

Detailed explanation-1: -Upon the incoming of water inside the guard cells, they swell up to become like a curved banana surface, due to which the stomatal pore opens up. When the guard cells lose water, they become flaccid and straight and thus, close the stomatal aperture. Guard cells and stomata regulates the respiration process in plants.

Detailed explanation-2: -Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing. Each guard cell has a relatively thick cuticle on the pore-side and a thin one opposite it.

Detailed explanation-3: -Potassium (K) is significant due to its function in controlling stomatal opening and shutting.
