Which gas do plants absorb from the atmosphere during photosynthesis?

During photosynthesis, plants absorb carbon dioxide from the atmosphere. This process occurs primarily in the leaves, where tiny openings called stomata allow carbon dioxide to enter. Inside the leaf, chlorophyll captures sunlight, which provides the energy needed to convert carbon dioxide and water into glucose and oxygen. The glucose serves as energy for the plant’s growth and development, while oxygen is released back into the atmosphere as a byproduct. This cycle is essential not only for plants but also for maintaining the balance of gases in our atmosphere, as plants play a crucial role in providing oxygen and utilizing carbon dioxide.
