Como respuesta a ciertos estímulos, los estoma se abren o se cierran, regulando los flujos de oxígeno, dióxido de carbono y vapor de agua. tiene el aumento de la intensidad luminosa sobre la apertura de los estomas. de realimentación que permiten controlar la apertura y el cierre de los estomas . parece que el mecanismo estomático ha evolucionado por este requisito. Las células guardas son células con forma de media luna, especializadas en controlar la apertura y cierre de los estomas en la epidermis del.
