Question

what is the role of stomata in photosynthesis and
detailed answer about 120-150 words​

Answer 1

Answer:

The gas exchange that occurs when stomata are open facilitates photosynthesis. Photosynthesis is the process by which plants convert sunlight into usable energy. During photosynthesis, carbon dioxide is taken in from the atmosphere through the stomata and oxygen is released as a waste product.

Answer 2

Stomata control the flow of gases in and out of leaves. During the day, when air temperatures rise and carbon dioxide levels are normal or above normal, the stomata open, allowing carbon dioxide to enter and photosynthesis to take place. Oxygen, a poisonous (to the plant) byproduct of photosynthesis, exits through the stomata. At night, the glucose recombines with oxygen, releasing energy as the glucose molecule breaks back into water and carbon dioxide. The excess water exits through the stomata in a process called transpiration. So, stomata do not directly participate in photosynthesis. However, the stomata control the influx of carbon dioxide, a critical component of photosynthesis, and allow the excess oxygen to exit. Stomata also control the flow of water vapor out of the leaf, limiting water loss during drought and allowing excess water to exit.
