They have "guard cells" surrounding an opening or pore which lets water vapor out and carbon dioxide in. When fluid pressure increases inside the stomata's guard cells, they swell up to open the pore.

How do plants breathe through stomata? Key regulators of stomata are plant vacuoles, fluid-filled organelles bound by a single membrane called the tonoplast. Plant vacuoles are fluid-filled ...

Beyond controlling stomatal (tiny pores for gas exchange) guard cells, FAMA also helps to produce myrosin cells—the specialized structures that store mustard oil compounds. So, when a plant is ...

Because of these properties, the majority of plant gas exchange occurs through stomata. Consequently, composition of cuticle and fast guard cell signaling are thought to be the major factors limiting ...
