• A. a - upper epidermis, b - waxy cuticle, c - stoma, d - air spaces, e -chloroplast
• B. a - upper epidermis, b - lower epidermis, c - guard cell, d - airspaces, e - chloroplast
• C. a - upper epidermis, b - lower epidermis, c - stoma, d - air spaces, e - nucleus
• D. a - waxy cuticle, b - upper epidermis, c - stoma, d - air spaces, e -nucleus

Answer 1

Answer:

B. a - upper epidermis, b - lower epidermis, c - guard cell, d - airspaces, e - chloroplast

In the cross-section of a leaf, the waxy cuticle prevents water loss, the upper epidermis provides structure, and the stoma allows for gas exchange. Option 2correctly labels these parts.
