Question

what is the \skin\ of a leaf called?
the mesophyll
the epidermis
stomata

Explanation:

To determine the "skin" of a leaf, we analyze the options:

• Mesophyll is the inner tissue of the leaf involved in photosynthesis, not the outer "skin".
• Epidermis is the outermost layer of cells in plants, acting as a protective covering (similar to skin) for the leaf.
• Stomata are small pores on the leaf surface for gas exchange, not the outer protective layer.

Answer:

B. The epidermis (assuming the options are labeled A, B, C with A: The mesophyll, B: The epidermis, C: Stomata)
