Hey there!
=>>> Guard cells regulate the opening and closing of the stomata and this regulation is brought about by the movement of water in and out of the guard cells. When water moves into the guard cells, they become flaccid. This causes the outer walls of cells bulge out and vice-versa.
=>> Rate of photosynthesis under the following conditions:
1) On cloudy day – Due to lack of light on cloudy day, the rate of photosynthesis decreases.
2) No rainfall in the area- Due to lack of water which is required by plants, the rate of photosynthesis decreases.
3) Good manuring in the area – If the soil has good amount of manure it becomes fertile. The good amount of humus is also made available to soil through manuring, then the soil is able to hold water which is required by plants. Thus, the rate of photosynthesis increases when good manuring is done.
4) Stomata get blocked due to dust- If the stomata present on the surface of leaves get blocked, the exchange of gases does not occur. So, carbon dioxide which is required by plants for performing photosynthesis is not made available to plants from surroundings. Thus, the rate of photosynthesis decreases when stomata get blocked due to dust.
Hope it helped!!!!!!!!!!☺️☺️☺️

when the plant take in water from the root and the water goes to the leaves it get stored into the guard cells and since the guard cells are tough from concave side and elastic from the convex side and that the two guard cell are attached toward each other then they sell up making some space for the stomata to open and gases to exchange.
in this situation rate of photosynthesis increases as it is very easy for the plant to do gas exchange
