CHALLENGE QUESTION:What is transpiration?
A
Process by which plants and trees remove water from soil
B
Process by which a plant “sweats”
C
Process by which a plant is transported to another soil sample
D
Process by which plants scientifically unwind
Explanation: 

Detailed explanation-1: -The process by which plants remove excess water through stomata present on the surface of leaves is called ‘transpiration’. Transpiration is essentially evaporation of water from leaves of the plant.

Detailed explanation-2: -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-3: -“Transpiration is the biological process by which water is lost in the form of water vapour from the aerial parts of the plants.”

Detailed explanation-4: -Maintaining plant structure – transpiration helps in maintaining the turgidity in plants since young plants that do not have woody stems need water for their structural support. Ensuring the cooling of plant – the loss of water in the form of water vapour from plants helps the plant to cool down during hot days.
