Question

3. Plants do not take in oxygen and give out
carbon dioxide during daytime. Does it mean
plants do not respire during day?​

Answer 1

Answer:

Plants respire throughout the day, while photosynthesis takes place only in the presence of sunlight. In the daytime, CO2produced during respiration is used by the plants in photosynthesis. So, CO2 is not released into the environment. The oxygen produced during photosynthesis, is released into the air through stomata.

Answer 2

Explanation:

plants plants do take in oxygen during the day to respire but this process in plants is not conducted as much as it is conducted in human beings as human beings need to do more activities done plants do.

plants conduct photosynthesis in on a much larger scale then respiration so we say that plants take in carbon dioxide and give out oxygen but the truth is they take in air out of which carbon dioxide is used for photosynthesis and some amount of oxygen is used for respiration.
