When photosynthesis takes place during the day, stomata will ____
A
open
B
close
C
static
D
hot
Explanation: 

Detailed explanation-1: -The stomata does not open during the day to avoid water loss and only opens during the night for carbon dioxide to enter the plant. The carbon dioxide is present as an intermediate inside the plant to perform photosynthesis during the day.

Detailed explanation-2: -Stomata also allow water vapor to escape from the leaf. In most plants stomata open during the day when photosynthesis takes place; thus, heat from the sun may cause considerable water loss through stomata.

Detailed explanation-3: -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-4: -Stomata provide for gas exchange and transpiration. Two guard cells that control the opening and shutting of the stomata surround it. For gaseous exchange and to release water vapor during transpiration, stomata open during the day. The change in the guard cell’s turgor pressure causes the stomata to open and close.

Detailed explanation-5: -Through photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores-called stomata-to take in carbon dioxide and release oxygen.
