Answer:
During transpiration the movement of potassium ions in and out of the guard cells causes the opening and closing of stomata. ... Due to this the water potential in the guard cells decreases and water moves inside the guard cells causing them to swell up and become turgid which in turn causes the opening of stomata pores.

Answer:
d..... Epidermal cells
Explanation:
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. ... The phototropins trigger many responses such as phototropism, chloroplast movement and leaf expansion as well as stomatal opening.
