What are mesophyll cells?
mesophyll. (Science: Plant Biology) tissue found inside leaves, consisting of photosynthetic (parenchyma) cells, also known as green-walled cells. Consists of relatively large, highly vacuolated cells with many chloroplasts. Includes palisade parenchyma and spongy mesophyll.
How does the opening and closing of the stomata happen?
The opening and closing of the stomata is guard cells. As water flows into the guard cells, they expand, and the curved surface causes the stomata to open. When guard cells lose water, they contract and become soft and straight, closing the stomata.
