TRANSPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Transpiration is a process of water loss in the form of ____ through ____ from plants to the atmosphere.
A
air vapour, respiration
B
water vapour, osmoregulation
C
air vapour, evaporation
D
water vapour, evaporation
Explanation: 

Detailed explanation-1: -Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is ‘pulled’ into the leaves.

Detailed explanation-2: -The loss of water in the form of water vapour from the aerial parts of a living plant is termed as transpiration. The water warmed by the sun turns into vapour and passes out through the aerial parts, mostly on the underside of the leaf surface.

Detailed explanation-3: -Transpiration is the evaporation of water from the spongy mesophyll cells followed by the diffusion of water through the air spaces and out of the stomata .

Detailed explanation-4: -It occurs mainly through the stomata in the leaves.

Detailed explanation-5: -Transpiration: Transpiration is the process by which plants lose water mainly via stomatal openings. Transpiration occurs from aerial parts of the plants such as stems, leaves, and flowers. 90% of water transpired from the plant via stomatal pores present in leaves.
