[A]: Wax, resin and suberin coating on the surface of plant parts reduce the rate of transpiration.
[R]: These adaptations are found mostly in xerophytes.

Mention three adaptations found in plants to reduce transpiration.

Transpiration has more than one purpose. Which of the following is not the purpose of transpiration? (a) Creates transpiration pull for absorption and transport in plants. (b) Cools leaf surfaces by evaporative cooling (c) Transports minerals from the soil to all parts of the plant. (d) Gives high tensile strength to water column present in xylem. (e) Translocation of sucrose from source to sink

Assertion :- In some xerophytic plants stem becomes green , flat,leaf like and leaves are modified into spines . Reason :-In xerophytic areas rate of transpiration is high , so plants develop various adaptions to minimize transpiration.
