How does a stomata open

WebTwo highly specialized cells, the guard cells that surround the stomatal pore, are able to integrate environmental and endogenous signals in order to control the stomatal aperture and thereby the gas exchange. The uptake of CO2 is associated with a loss of water by leaves. Control of the size of the stomatal aperture optimizes the efficiency of water use … WebOpening and closure of the stomatal pore are mediated by changes in the turgor pressure of the two guard cells. The turgor pressure of guard cells is controlled by movements of large quantities of ions and sugars into and out of the guard cells.

During water stress the stomatal pore can be closed to reduce water loss. By closing the stomatal pore the water use efficiency is increased ( Farooq et al., 2009 ), reducing the amount of water lost per CO 2 molecule assimilated.

WebOsmosis, which depends on the potassium concentration in the cells, rushes water into the guard cells for stomata opening. Potassium must be actively transferred to the vacuoles for the stomata to open. This increases the potassium concentration in the cells and encourages water entry by osmosis, raising cell turgency and exposing the pores. WebSolution.
