Photosynthesis in guard cells leads to the production of :-

Correct option is B

Ans.(b) Sugar

Explanation:
The correct answer is Sugar. Photosynthesis in guard cells leads to the production of glucose (sugar), which plays a key role in the opening and closing of stomata. During the daytime, photosynthesis in chloroplasts of guard cells produces glucose, which increases osmotic pressure, causing water to enter the cells by osmosis. This results in the swelling of guard cells, leading to stomatal opening for gas exchange.

Information Booster:
● Guard cells regulate the opening and closing of stomata.
● Stomatal opening allows carbon dioxide intake for photosynthesis.
● The accumulation of sugar increases turgor pressure, opening the stomata.
● When sugar levels drop, water exits, and the stomata close.
● Guard cells contain chloroplasts, enabling photosynthesis.
● Stomata are crucial for transpiration and temperature regulation.
● Environmental factors like light and CO₂ concentration influence stomatal movement.
