Question

Small waxy leaves are a likely plant adaption to

• A. Reduce the surface on which frost can form
• B. Reduce the amount of moisture loss through transpiration
• C. Reduce the amount of water absorbed during heavy rain
• D. Increase the strength of leaves in a windy environment

Answer 1

Answer: (B)

Reduce the amount of moisture loss through transpiration

The plants which grow in the temperate regions have developed specialised characters from the prevention of loss of water. When the leaves are small or transformed into spines. There is a waxy material which is known as the cuticle present on the surface of the leaves. This waxy covering helps to prevent water loss from the plant in the form of water vapour through transpiration.

Thus, the correct answer is option B.
