1.	Transpiration types signifocance closing and opening of stomata
Answer» Massive amounts of gaseous exchange takes place in the leaves through tiny pores called stomata for the purpose of photosynthesis. The opening and closing of stomatal pores is controlled by the guard cells, when water flows into the guard cells, they swell, become curved and cause the pore to open whereas when the guard cells lose water, they shrink, become straight and close the stomatal pore.
