What name is given to the pores in the surface of a leaf that allow gases in and out?

Answer:

The pores in the surface of a leaf that allow gases in and out are called stomata.

Explanation:

  • Function: Stomata are tiny openings primarily involved in gas exchange. They allow carbon dioxide (CO_2) to enter the leaf for photosynthesis, and oxygen (O_2) and water vapor to exit.

  • Location: Found mostly on the underside of leaves to minimize water loss due to evaporation.

  • Structure: Each stoma (singular of stomata) is flanked by two guard cells, which expand or contract to open or close the pore.

  • Regulation: The opening and closing of stomata are regulated by the turgidity of the guard cells. This process is influenced by environmental factors like light, carbon dioxide concentration, and humidity.
