Question

How transpiration takes place through stomata . Describe with the help of diagram mechanism for opening and closing of stomata?​

Answer 1

Answer:

The opening and closing of stomata operate as a result of turgidity changes in the guard cells. During the daytime, the guard cells perform photosynthesis due to which osmotic pressure increases. Thus, the guard cells absorb water from the neighboring cells.

Hope it helps

Answer 2

Answer:

Stomata – Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease
