Question

What happens to stomata in the light?

Answer 1

Answer:

It opens up and the process of transpiration occurs.

If it is exposed to continuous light photo-oxidation takes place and if it does not get enough light etiolation takes place.

Answer 2

Light and drought typically have an adverse effect on stomatal mobility.

Light affects stomata:

• Light, including blue and red light, causes stomata to open.
• Through photosynthesis in the chloroplasts of the mesophyll and guard cells, red light triggers stomatal opening.
• Blue light, on the other hand, signals stomatal opening.
• A pair of sausage-shaped guard cells surround each stoma.
• The guard cells osmotically absorb water in intense light, becoming plump and turgid.
• The guard cells dry out and become floppy in low light, which causes the stomata to close.

Stomata:

• In the epidermis of tree leaves and needles, there are cell structures called stomata that play a role in the exchange of water and carbon dioxide between plants and the atmosphere.
• Stomata, the tiny pores on the outside of leaves and stalks, control how gases enter and exit leaves and therefore, how plants as a whole function.
• In all periods, ranging from minutes to millennia, they adjust to regional and global changes.
