WebOpening and closing of stomata occurs due to turgor changes in guard cells. When guard cells are turgid, stomatal pore is open while in flaccid conditions, the stomatal aperture … WebRole of potassium K+ in stomatal opening is now universally accepted. This was observed for the first time by Fujino (1967) that opening of stomata occurs due to the influx of K + ions into the guard cells.. The sources of K + ions are nearby subsidiary and epidermal cells, thereby increasing the concentration from 50 mM to 300 mM in guard cells. The increase …
Web29 de mar. de 2024 · Answer -. The guard cells of the stomata swell when water flows into them , causing the stomatal pore to open. Similarly the pore closes if the guard cells shrink. Thus, opening and and closing of stomatal pore depends on water content in the guard cells. So, the correct answer is (d) WebThis response was reversible. All species responded in the same way. The opening of stomata with increasing temperature was apparently independent of the stomatal response regulated by atmospheric humidity. At high plant water stress, the stomatal response was reversed, i.e., the stomata closed when temperature was gradually increased.
