Question

Is stomata required for photosynthesis outside of the fact that it helps in respiration?

Answer 1

Answer:

Just as animals breath, plants do so too through the stomata. The gaseous exchange that they are responsible for, facilitate photosynthesis by letting in the essential CO2. Carbon dioxide is used as the fuel to drive photosynthesis, which generates oxygen as a byproduct, which is then released to the atmosphere. Now, how can stomata facilitate photosynthesis? They can do so by playing an important role in transpiration. Transpiration is defined as the absorption of water into the plant, its distribution within it and its final release to the atmosphere from the areal parts. Transpiration through stomata, creates a water potential within the plant, which in turn, favors the passive water absorption in the roots, which will then be transported throughout the plant by the Xylem.

To perform photosynthesis, plants need six molecules of water and six molecules of CO2 to produce sugar and oxygen. Therefore, as mentioned, stomata play an integral part in water and CO2, entry to the plant, thus having facilitating photosynthesis.

Answer 2

Plants respire through plant pores, called stomata. During respiration and photosynthesis, gases go in and out of the plants through stomata using diffusion, not breathing.
