Table 1 compares some features of a typical prokaryotic bacterial cell and a typical eukaryotic animal cell.
| Feature | Prokaryotic cell | Eukaryotic cell |
|---|---|---|
| Diameter | 1–5 µm | 10–100 µm |
| Nucleus | No membrane-bound nucleus; DNA in nucleoid | Membrane-bound nucleus present |
| Membrane-bound organelles | Absent | Present (e.g., mitochondria, endoplasmic reticulum) |
| Ribosome size | 70S | 80S |
| Cell wall composition (if present) | Peptidoglycan | No cell wall (animal cells) or cellulose (plant cells) |
| DNA structure | Circular, not associated with histone proteins | Linear, associated with histone proteins |
Outline the key differences between prokaryotic and eukaryotic cells that are shown in the table.
