Answer:Water conservation
Explanation:
In some of the higher plants there is a presence of hard cutaneous part on the leaves. Cuticle is a water-impervious layer which covers the epidermal cells of the leaves.
It aids in limiting the water loss by the leaves. It is the part of plants that faces the external environment by hindering the water loss.
This part is made up of waxy coating, which is water repellent known as suberin.
It helps in the water conservation as it limits the excess loss of water from leaves.
