Which materials pass through the stomata during photosynthesis?

• A. Nitrogen and glucose
• B. Oxygen and water vapor
• C. Glucose and oxygen
• D. Carbon dioxide and water vapor

Answer: (D)

Verified step by step guidance

1. Understand the role of stomata: Stomata are small openings on the surface of leaves that facilitate gas exchange between the plant and the environment.
2. Identify the gases involved in photosynthesis: Photosynthesis primarily involves the uptake of carbon dioxide (CO₂) from the atmosphere and the release of oxygen (O₂) as a byproduct.
3. Recognize the role of water vapor: Water vapor is also released through stomata during transpiration, which is a process that occurs alongside photosynthesis.
4. Eliminate incorrect options: Nitrogen and glucose are not directly involved in the gas exchange through stomata during photosynthesis. Glucose is produced inside the plant cells, not exchanged through stomata.
5. Conclude with the correct materials: The correct materials that pass through the stomata during photosynthesis are carbon dioxide (CO₂) entering the plant and water vapor (H₂O) exiting the plant.
