Detailed explanation-1: -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-2: -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).

Detailed explanation-3: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-4: -A new study involving ANU and international collaborators has found plants release more carbon dioxide into the atmosphere through respiration than expected. Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration.

Detailed explanation-5: -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.
