Although transpiration cannot be avoided, plants can minimize their water loss by controlling how wide their stomata are open, as well as what time of day they are open. There are various types depending on the arrangement of subsidiary cells with respect to guard cells. Each stoma is surrounded or enclosed by two kidney-shaped cells called the guard cells. Q.13 Mention the three elements of Xylem tissue. The guard cell shape depends on how much water and potassium are present in the cells. Stomata play an important role in gaseous exchange and photosynthesis. Regina Bailey .
