Stomata are cellular breathing pores on leaves that open and close to absorb photosynthetic carbon dioxide and to restrict water loss through transpiration, respectively. Grasses (Poaceae) form morphologically innovative stomata, which consist of two dumbbell-shaped guard cells flanked by two lateral subsidiary cells (SCs).

網頁2010年2月23日 · Stomata are composed of paired, symmetric guard cells that operate by changing turgor pressure, a system that forms an effective fail-safe against dehydration, since low turgor closes stomata.
