As we have learned

Stomata -

Stomata are tiny pores, composed of two bean shaped epidermal cells called guard cells which encloses stomal pore. 

- wherein

Stomata are present in aerial part of young stems and leaves and absent in roots. The movement of stomata depends upon the turgidity (open) and flaccid (closed) of guard cells. Turgidity in guard cells cause radial orientation of cellulose, microfibrils in the cell wall, results opening of stomata.
