Question

question 5 of 6
what cooling process involves water vapor
exiting from the underside of leaves through
small openings?
transpiration
photosynthesis
condensation
absorption

Explanation:

To solve this, we analyze each option:

• Transpiration: The process where water vapor exits leaves (via stomata, small openings) and cools the plant. This matches the description.
• Photosynthesis: Converts light to energy, uses CO₂, produces glucose/O₂—no water vapor exit for cooling.
• Condensation: Gas to liquid (e.g., dew), not leaf - related water vapor exit.
• Absorption: Roots take in water/minerals, not vapor exit from leaves.

Answer:

Transpiration
