NEET BIOLOGY

Detailed explanation-1: -Plants breathe in oxygen and give out carbon dioxide. But during the day, the amount of carbon dioxide released is much less than the amount required for photosynthesis. So, plants take in carbon dioxide from the atmosphere for preparing food.

Detailed explanation-2: -The Process of Respiration in Plants Leaves possess stomata – tiny pores, for gaseous exchange. The oxygen consumed via stomata is used up by cells in the leaves to disintegrate glucose into water and carbon dioxide.

Detailed explanation-3: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Detailed explanation-4: -Plants help us breathe by taking in carbon dioxide (for photosynthesis) and letting out oxygen through their leaves. This process is called plant respiration.

Detailed explanation-5: -The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.
