Hello Mate! Here is your answer:
The above shown diagram is the structure of stomata which is present in the leaf on a plant. Through this stomata, the plants respire and breath. In other words, exchange of gases mostly takes place through these tiny pores present on the leaf tips. The Stomata has two kidney shaped structures called as Guard Cells. These cells are very crucial as they have a significant role in stomata. They bulge and contract to open and close the Stomata with respect to time. They gain water and bulge so as to keep the Stomata open like we can see in the first diagram. In the second diagram, it is clearly shown that the guard cells lose their water and so their turgidity which forces them to close the Stomata. Chloroplast is also there which is a cell organelle that traps in the sunlight and has Chlorophyll by which they prepare their own food.
I hope this helps.
