Question

what three structures are found in plant cells but not animal cells?
a plasma membrane, central vacuole, nucleus
b central vacuole, mitochondria, cytoplasm
c cell wall, central vacuole, plastids
d cytoplasm, endoplasmic reticulum, mitochondria

Explanation:

• Plasma membrane and nucleus are present in both plant and animal cells. So option a is incorrect.
• Mitochondria and cytoplasm are found in both plant and animal cells. So option b is incorrect.
• Cytoplasm, endoplasmic reticulum, and mitochondria are present in both plant and animal cells. So option d is incorrect.
• Cell wall (provides structural support), central vacuole (stores substances), and plastids (e.g., chloroplasts for photosynthesis) are unique to plant cells.

Answer:

C. cell wall, central vacuole, plastids
