    The cuticle is found at the top of the leaf and prevents water from leaving the leaf by evaporation. The picture below illustrates one of the features of the cuticle that aids in its function. The best description for this feature is  - ProProfs

    The cuticle is found at the top of the leaf and prevents water from leaving the leaf by evaporation. The picture below illustrates one of the features of the cuticle that aids in its function. The best description for this feature is 

    • The cuticle is composed of a waxy substance which prevents water loss.

    • The cuticle is composed of a hydrophilic substance so water can pass readily through the cuticle

    • The cuticle offers protection since it is very flexible.

    Correct Answer
    A. The cuticle is composed of a waxy substance which prevents water loss.
  • 5. 

    The prefix auto in the term autotroph, refers to the facts that autotrophs
