Which three nutrients do plants take up directly from the atmosphere?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Plants absorb three essential nutrients directly from the atmosphere: carbon (C), hydrogen (H), and oxygen (O). Carbon dioxide is absorbed through leaf stomata during photosynthesis, where it combines with water to produce glucose and oxygen. Oxygen is absorbed for respiration, and hydrogen comes from water vapor and water absorbed by roots. These three elements constitute the majority of plant dry matter and are fundamental to all organic molecules in plants.
