Stomata primarily perform the function of gas exchange during photosynthesis. They are small openings on the surface of leaves that allow for the exchange of gases, primarily carbon dioxide and oxygen. Here’s how the functions relate to photosynthesis:
-
Absorbing water: This is primarily done by the roots of the plant through root hairs, not by the stomata.
-
Producing glucose: While photosynthesis results in glucose production, this is not a function performed by the stomata. Instead, glucose is produced in the chloroplasts within the leaf cells.
-
Gas exchange: Stomata allow carbon dioxide to enter the leaf and oxygen to exit, which are essential processes for photosynthesis.
-
Capturing light energy: Light energy is captured by chlorophyll in the chloroplasts, not by the stomata.
Therefore, the correct function of stomata in relation to photosynthesis is gas exchange.
