Question

Leaves release more water vapour from the undersurface because?​

Answer 1

Explanation:

As the sun warms the water inside the plants leaves, transpiration occurs. This warming causes most of the water to turn into vapor and evaporate. The water vapor escapes into the air through the stomata. The water vapor absorbs heat as it escapes, which cools the inside of the leaves.

Answer 2

Explanation:

The water eventually is released to the atmosphere as vapor via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.
