Detailed explanation-1: -The correct option is (C). Stomata are tiny pores present in the epidermis of leaves. They are mainly for gaseous exchange in plants and for controlling the rate of transpiration. Stomata do not help in photosynthesis directly.
Detailed explanation-2: -It does not prevent the exchange of gases. The gaseous exchange involves the exchange of oxygen and carbon dioxide between plants and the environment. The loss of water and the exchange of gases occurs through stomata.
Detailed explanation-3: -In this reaction, the excess water gets released through the stomata again. The water gets evaporated into the atmosphere with the help of a process called transpiration. In conclusion, it does not play a direct role in photosynthesis but is an important organelle.
Detailed explanation-4: -Stomata are cell structures in the epidermis of tree leaves and needles that are involved in the exchange of carbon dioxide and water between plants and the atmosphere.
