What gas do plants absorb from the atmosphere?

• A. Oxygen
• B. Carbon Dioxide
• C. Hydrogen
• D. Nitrogen

Answer: (B)

Plants absorb carbon dioxide from the atmosphere as a crucial part of the process of photosynthesis. During this process, plants take in carbon dioxide through small openings in their leaves known as stomata. They use sunlight to convert this carbon dioxide, along with water absorbed through their roots, into glucose (a type of sugar) and oxygen. The glucose produced serves as food for the plant, fueling its growth and energy needs, while the oxygen is released back into the atmosphere as a byproduct. This exchange is vital not only for the plants themselves but also for maintaining the balance of gases in the environment, as it contributes to the oxygen supply that many living organisms depend on.
