Stomata:

  1. Stomata are cellular openings present in the epidermis layer of the leaves.
  2. It is surrounded by guard cells that regulate the opening and closing of the stomatal pores.
  3. They help in obtaining the carbon dioxide required for conducting photosynthesis.
  4. During the day, the stomata are open and the exchange of gases occurs while water is lost through the open pore.
  5. During the night, photosynthesis doesn't occur due to the lack of sunlight to prevent water loss.
