NEET BIOLOGY

Detailed explanation-1: -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-2: -Plants take in oxygen and give out carbon dioxide during respiration all the time.

Detailed explanation-3: -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-4: -Plants take in carbon dioxide to use for photosynthesis. At the same time, as they grow and burn energy, they release carbon dioxide back into the air in a process known as respiration. It happens in rainforests, grasslands, tundras and deserts-anywhere vegetation can be found.

Detailed explanation-5: -CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation. CO2 plays various roles in the human body including regulation of blood pH, respiratory drive, and affinity of hemoglobin for oxygen (O2).
