Detailed explanation-1: -In photosynthesis, solar energy is harvested and converted to chemical energy in the form of glucose using water and carbon dioxide. Oxygen is released as a byproduct.

Detailed explanation-2: -18 November 2017. Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration.

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: -Photosynthesis is a process by which green plants prepare their own food from carbon dioxide and water in the presence of sunlight. During this process, oxygen is released.

Detailed explanation-5: -Detailed Solution. The correct answer is Twilight. During 24 hours there is a time when plants neither release O2 nor CO2. This is the time of Twilight.
