The table below shows some features of a prokaryotic cell (bacterium) and a eukaryotic cell (an animal cell). For each feature, describe one similarity and one difference between the two cell types.
| Feature | Prokaryotic cell | Eukaryotic cell |
|---|---|---|
| Size | 1–5 μm | 10–100 μm |
| DNA location | Circular DNA in nucleoid, not enclosed by membrane | Linear DNA enclosed within a nuclear envelope |
| Ribosomes | 70S ribosomes | 80S ribosomes |
| Membrane-bound organelles | None | Present (e.g., mitochondria, Golgi body) |
| Cell wall | Present (peptidoglycan) | Absent in animal cells |
