Final answer:
Plants absorb carbon dioxide through photosynthesis, taking it in through stomata on leaves and converting it into glucose and oxygen using sunlight and chlorophyll. They also release some carbon dioxide through cellular respiration, but the amount is usually less than what is absorbed.
Step-by-step explanation:
Plants absorb carbon dioxide through a process calledphotosynthesis. During photosynthesis, plants take in carbon dioxide from the air through stomata, tiny openings on the surface of leaves. Inside the leaves, carbon dioxide combines with water to form glucose and oxygen in the presence of sunlight and chlorophyll.
The glucose produced during photosynthesis is used by plants as an energy source for growth and cellular activities. Additionally, plants release oxygen back into the atmosphere, which is essential for the survival of many organisms, including humans.
On the other hand, plants also release some carbon dioxide as a byproduct ofcellular respiration, a process that occurs in all living cells to produce energy. However, the amount of carbon dioxide released through cellular respiration in plants is typically much less than the amount absorbed through photosynthesis.
