4. If plant roots are exposed to air and sunlight for a few minutes, and then the plant is placed back in the soil, it will wilt before starting to recover. What is happening at the cellular/tissue level in the roots?

Explanation:

If plant roots are exposed to air, particularly non woody plants that rely on water pressure to stay erect, they start to wilt because of the disruption between the balance of transpiration (loss of water through the stomata) and absorption of water by the roots.

Since the plant's root has been exposed, they are no longer able to absorb water, and then transpiration also occurs which leads to a faster loss of water causing the plants cells to become dehydrated and collapse leading to wilting of the plants.

But if water is provided immediately, they can recover
