Which organelle makes the difference between a plant cell and an animal cell?
Think it through first, then pick an option.
- a Mitochondria
- b Endoplasmic reticulum
- c Plastid
- d Ribosome
Answer and explanation
Correct answer: c Plastid
Plastids occur only in plant cells and not in animal cells, so they mark the difference.
Why the other options are wrong
- a Mitochondria: Mitochondria are found in both plant and animal cells, so they do not distinguish them.
- b Endoplasmic reticulum: The ER occurs in both kinds of cell, so it is not the difference.
- d Ribosome: Ribosomes are in both plant and animal cells, so they do not make a difference.
