Guard cells open stomata by actively pumping in solutes to increase turgor in favorable conditions; low turgor closes the pore due to asymmetric cell wall configuration.
Las células oclusivas abren los estomas bombean solutos activamente para aumentar la turgencia cuando las condiciones son favorables; la baja turgencia cierra el poro debido a la configuración asimétrica de las paredes celulares.
