Stomata are pores in the epidermis of leaves through which
gaseous exchange takes place. Each stoma is surrounded by a
guard cell,the guard cell controls the size of the stoma by
changes in their turgidity and flaccidity. in warm
temperatures the rate of transpiration(water loss)is high.
Therefore the plants become flaccid,the guard cell sag,
inner cell walls come closer and the stoma close.
in cool temperatures,water from the surroundings enter the
cell of plants by osmosis. The cell of the plant becomes
turgid,the guard cell expands,inner cells become tough and
stoma opens.
