Question

what is function of Stomata?
​

Answer 1

Structure and function of stomata :

➡️The stomata control gas exchange in the leaf. Each stoma can be open or closed, depending on how turgid its guard cells are.

➡️The stomata can open and close to:

▪️Control water lost by transpiration

▪️Allow gas exchange

➡️Diffusion of carbon dioxide into the leaf for photosynthesis and oxygen and water vapour out of the leaf, is greatest when the stomata are open during the day.

➡️Stomata are found mainly on the lower surface of the leaf to reduce water loss by transpiration.

Answer 2

Answer:Stomata are the tiny openings or pores in plant tissues that allow gaseous exchange. They are typically found in plant leaves or sometimes may also be found in some stems.

There are various types of stomata:

- Anomocytic Stomata: They are surrounded by epidermal cells with fixed shape and size.

- Anisocytic Stomata: Each stoma is surrounded by unequal sized three subsidiary cells.

- Diacytic Stomata: These are surrounded by a pair of subsidiary cells that are perpendicular to guard cells.

- Paracytic Stomata: They are surrounded by two subsidiary cells.

- Gramineous Stomata: Each stoma possesses two guard cells.
