NEET BIOLOGY

Detailed explanation-1: -Plants absorb carbon dioxide from the air through tiny pores called stomata.

Detailed explanation-2: -Plants, like animals, take in oxygen and give out carbon dioxide during respiration. Only during photosynthesis, plants take in carbon dioxide and release oxygen as a byproduct.

Detailed explanation-3: -During photosynthesis, plants take in carbon dioxide and oxygen is released as a byproduct. Plants prepare their food from carbon dioxide and water in the presence of sunlight and chlorophyll.

Detailed explanation-4: -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-5: -From the above information we have found that carbon dioxide is not released during photosynthesis. Instead of it oxygen is released. Hence, the correct answer is option (B).
