One Important Difference Between the Anatomy of Roots and the Anatomy

Question

One important difference between the anatomy of roots and the anatomy of leaves is that
A)only leaves have phloem and only roots have xylem.
B)root cells have cell walls and leaf cells do not.
C)a waxy cuticle covers leaves but is absent from roots.
D)vascular tissue is found in roots but is absent from leaves.
E)leaves have epidermal tissue but roots do not.

Accepted Answer

A waxy cuticle covers leaves but is absent from roots. This is an important difference in the anatomy of roots and leaves as it helps prevent water loss from the leaves through transpiration. The absence of a cuticle on roots is not necessary as they are typically in contact with soil moisture.
