The structure of stomatal guard cells affects their function.

Description
When flaccid, guard cells close stomatal pores. Turgid guard cells produce a stomatal opening. (a) An SEM of a stoma in a rose leaf, showing the two guard cells bordering a partly open pore. (b) Thickened inner cell walls and radial orientation of cellulose microfibrils in the guard cell walls explain why they separate when turgid, forming a pore.
