Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where is evaporation takes place at a plant?
A
trunk
B
root
C
under the leaves
D
surface of leaves
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: -Effects of Leaf Anatomy on the Distribution of Evaporation. Our model predicted that evaporation is highly concentrated at the lower epidermis and the bundle sheath (BS), with some evaporation occurring from across the mesophyll but especially in the upper spongy mesophyll, just below the palisade/spongy transition.

Detailed explanation-3: -Dave Campbell explains that evaporation occurs when water changes from a liquid state to a gaseous state. It can happen anywhere there is water – in the soil, lakes, oceans and plants. When it occurs in plants, water is lost through microscopic pores in the plant’s leaves (stomata).

Detailed explanation-4: -Transpiration. The loss of water through evaporation from the surface of plants is called transpiration.

Detailed explanation-5: -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.
