What is transpiration in the context of photosynthesis?

• A. The release of water vapor from plant leaves into the atmosphere
• B. The process by which plants convert sunlight into chemical energy
• C. The absorption of carbon dioxide from the atmosphere by plant leaves
• D. The transport of nutrients from the soil to the plant leaves

Answer: (A)

Verified step by step guidance

1. Understand that transpiration is a process related to water movement in plants, not directly to the conversion of sunlight into energy.
2. Recognize that transpiration involves the movement of water through a plant and its evaporation from aerial parts, especially from the leaves.
3. Identify that the primary function of transpiration is to release water vapor into the atmosphere, which is a key part of the water cycle.
4. Differentiate transpiration from photosynthesis, which is the process where plants convert sunlight into chemical energy.
5. Clarify that while transpiration involves water vapor release, photosynthesis involves the absorption of carbon dioxide and the production of oxygen and glucose.
