AThe xylem tissue
BThe waxy cuticle
CThe mesophyll layer
DThe epidermis layer
Answer & Solution
Correct answer: C. The mesophyll layer
1. Leaves consist of several layers of cells.
2. The mesophyll is the middle layer of chlorophyll-rich cells in a leaf.
3. Photosynthesis occurs in that middle layer.
4. Chloroplast-containing cells in plants exist in the mesophyll, which is why the process is sited there.
