When the plant becomes dehydrated and …
WebUpon the incoming of water inside the guard cells, they swell up to become like a curved banana surface, due to which the stomatal pore opens up. When the guard cells lose water, they become flaccid and straight and thus, close the stomatal aperture. Guard cells and stomata regulates the respiration process in plants. WebSep 9, 2024 · Why must stomata be closed on hot dry days? During hot dry conditions, the stomata close its opening to conserve water. The humidity around the leaves is affected by the temperature of the air around it. But in case the water is less, these guard cells don’t swell and hence the stomata remain closed so that the plant does not lose water.
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 …
