Question

What happens to stomata if a plant lacks water?

Answer 1

Stomata:

1. Stomata are small apertures found on the epidermis of leaves.
2. Under a light microscope, we can observe stomata.
3. Stomata can be seen on stems and other plant components in some plants.
4. Stomata are essential for gas exchange and photosynthesis.

When a plant lacks water:

1. When a plant lacks water, stomata close because there is insufficient water to provide pressure in guard cells, allowing stomata to open.
2. Plants use this reaction to preserve water.
3. Water loss from leaves rises at high temperatures.
4. Because there is less water available, the guard cells become floppy and shut.
