Both Assertion And Reason Are CORRECT, But The Reason Is NOT CORRECT  Explanation Of The Assertion.

• Transpiration is the loss of water in the form of water vapour through the aerial parts of a plant.
• Stomatal transpiration takes place through the small pores known as stomata in leaves.
• This occurs when the stomata opens for letting the carbon dioxide inside during photosynthesis. It is considered to be a cost that the plants need to pay for photosynthesis.
• Transpiration pull leads to the upward movement of water through the xylem and results in loss of more water.
• This in turn helps in cooling the plants and their associated environment.
