Common Structures in Animal and Plant Cells

Steps:

• Classify liver cell as an animal cell from mammals.
• Classify leaf cell as a plant cell from vegetation.
• List shared eukaryotic features: nucleus, cytoplasm, mitochondria.
• Match options to shared features, selecting cytoplasm as universal.

Why C is correct:

• Cytoplasm is the fluid matrix filling all eukaryotic cells, enabling organelle suspension and metabolic reactions in both animal and plant types.

Why the others are wrong:

• A: Cell wall provides rigid support only in plant cells, absent in animal cells.
• B: Chloroplasts perform photosynthesis exclusively in plant cells, not in animal cells.
• D: Sap vacuole stores water and nutrients primarily in plant cells, unlike the smaller vacuoles in animal cells.

Final answer: C
