NEET BIOLOGY

Detailed explanation-1: -When there is less water available for the plants, dehydrated mesophyll cells release the plant hormone abscisic acid, which causes the stomatal pores to close and reduces water loss during oxygen release and carbon dioxide intake. Additionally, it aids in keeping the plant cells turgid.

Detailed explanation-2: -When a plant wilts (shrivels), the stomata closes. How does this help the plant? It reduces further water loss during transpiration.

Detailed explanation-3: -Water loss through transpiration can be reduced by closing the stomata in the leaves using a substance called ABA. When the stomata is closed photosynthesis will decrease because no CO2 can enter through the closed stomata.

Detailed explanation-4: -Stomata are tiny holes found in the underside of leaves. They control water loss and gas exchange by opening and closing. They allow water vapour and oxygen out of the leaf and carbon dioxide into the leaf.

Detailed explanation-5: -The loss of water as vapor from plants at their surfaces, primarily through stomata. rates increase; when they are closed, transpiration rates decrease.
