What occurs during transpiration in plants?

• A. Water vapor is released from plant leaves into the atmosphere.
• B. Glucose is transported from the leaves to other parts of the plant.
• C. Carbon dioxide is absorbed by plant roots from the soil.
• D. Oxygen is produced in the chloroplasts during photosynthesis.

Answer: (A)

Verified step by step guidance

1. Understand the concept of transpiration: Transpiration is the process by which water vapor is released from the aerial parts of plants, primarily through small openings called stomata on the leaves.
2. Identify the role of stomata: Stomata are tiny openings on the surface of leaves that allow for gas exchange. During transpiration, they open to release water vapor into the atmosphere.
3. Consider the environmental factors: Transpiration rates can be influenced by environmental conditions such as temperature, humidity, wind, and light. Higher temperatures and wind can increase transpiration rates.
4. Recognize the importance of transpiration: Transpiration helps in cooling the plant, maintaining nutrient uptake, and driving the flow of water and minerals from roots to leaves.
5. Differentiate transpiration from other processes: Unlike photosynthesis, which involves the production of oxygen and glucose, transpiration specifically involves the release of water vapor, not the transport of glucose or absorption of carbon dioxide.
