Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where is evaporation takes place in a plant?
A
trunk
B
root
C
surface of leaves
D
None of the above
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Our results corroborate earlier predictions that most evaporation occurs from the epidermis at low light and moderate humidity but that the mesophyll contributes substantially when the leaf center is warmed by light absorption, and more so under high humidity.

Detailed explanation-3: -As evaporation occurs at the leaf surface, the properties of adhesion and cohesion work in tandem to pull water molecules from the roots, through xylem tissue, and out of the plant through stomata.

Detailed explanation-4: -Plants absorb water from the soil for the synthesis of carbohydrates as well as they evaporate from leaves in large amounts through stomata. This process of evaporation of water from leaves is called transpiration.

Detailed explanation-5: -Transpiration. The loss of water through evaporation from the surface of plants is called transpiration.
