AThe adaxial surface
BThe abaxial surface
CThe proximal surface
DThe cuticular surface
Answer & Solution
Correct answer: B. The abaxial surface
1. The epidermis covers both sides of a leaf and each side has a technical name.
2. The upper side is the adaxial surface, also called the adaxis.
3. The lower side is the abaxial surface, also called the abaxis.
4. So the answer for the lower side is abaxial.
5. Adaxial is the trap, because the two words differ by two letters and name opposite faces.
6. The cuticle is a waxy layer present on leaf surfaces rather than a name for one side of the leaf.
