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 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-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 – or ‘fix’ – carbon dioxide from the atmosphere during photosynthesis. Some of the carbon is used for plant growth, and some of it is used in respiration, where the plant breaks down sugars to get energy.

Detailed explanation-5: -Carbon dioxide is released during breathing when oxygen is taken in. Carbon dioxide gas turns lime-water milky. The fact that carbon dioxide is produced during respiration can be shown by demonstrating the effect of inhaled air and exhaled air on lime-water.
