DENDROLOGY

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 breathe in oxygen and give out carbon dioxide. But during the day, the amount of carbon dioxide released is much less than the amount required for photosynthesis. So, plants take in carbon dioxide from the atmosphere for preparing food.

Detailed explanation-3: -All plants give out oxygen during day and carbon dioxide during night.

Detailed explanation-4: -It’s true that plants love CO2. During photosynthesis, they take in carbon dioxide and, with the assistance of water and sunlight, make energy for themselves while releasing oxygen for us to breathe.
