explain the stomatal moment
Answers
Answer:
the stomatal opening and closing depends on the generation of a potassium ion gradient. ATP produced in the guard cells during photosynthesis is utilised to pump the potassium ions of the adjacent cells into the guard cells. ... Thus, the guard cells become turgid, widening the stomatal opening.

The process of opening or closing of stomata, which is directly related to the stomatal conductance (measuring rate of passage of either water vapor or carbon dioxide (CO2) through stomata). Among these, abscisic acid (ABA), is the best-known stress hormone that closes the stomata, although other phytohormones, such as jasmonic acid, brassinosteroids, cytokinins, or ethylene are also involved in the stomatal response to stresses. When the plant has enough water in its cells the guard cells swell up and open the stomata. When the plant isn't getting enough water the guard cells can't swell and the stomata stay closed, so the plant doen's lose water. But if the stomata are closed photosynthesis can't happen and eventually the plant might starve.
