NEET BIOLOGY

Detailed explanation-1: -Stomata remains close during the day time to prevent the loss of water by transpiration. They store the CO2 in their cells until the sun comes out and they can carry on with photosynthesis during the day time.

Detailed explanation-2: -Two Main Functions of Stomata In many plants, stomata remain open during the day and closed at night. Stomata are open during the day because this is when photosynthesis typically occurs. In photosynthesis, plants use carbon dioxide, water, and sunlight to produce glucose, water, and oxygen.

Detailed explanation-3: -2.2. 1). Stomata must open to allow the gas exchange of carbon dioxide and oxygen for efficient photosynthesis (see Photorespiration), and light thus typically triggers stomatal opening.

Detailed explanation-4: -Stomata is open during the daytime to allow gas exchange. Photosynthesis occurs during the day and thus stomata are open to supply the carbon dioxide required for the process. The stomatal openings remain closed at night as photosynthesis is not conducted without sunlight.

Detailed explanation-5: -Stomata are pores on the leaf surface, which are formed by a pair of curved, tubular guard cells; an increase in turgor pressure deforms the guard cells, resulting in the opening of the stomata.
