AQA GCSE Eukaryotic and Prokaryotic cells (Biology)
Eukaryotic cells
All Eukaryotic cells have a cell membrane, cytoplasm and their genetic material is found inside the nucleus.
Examples of Eukaryotic cells include plant and animal cells.
Prokaryotic Cells.
Prokaryotic cells are smaller than Eukaryotic cells.
Prokaryotic cells have cell membrane, cytoplasm, cell wall.
The genetic material of a prokaryotic cell is not enclosed in a nucleus. Instead it is a single DNA loop in the cytoplasm. Prokaryotic cells may also contain rings of DNA called plasmids.
Examples of Prokaryotic cells include Bacteria.
| Eukaryotic cells | Prokaryotic Cells |
|---|---|
| Larger | Smaller |
| Contains cell membrane, cytoplasm and nucleus | Contains cell wall, cell membrane and cytoplasm. There is NO nucleus |
| Genetic material is in a nucleus | Genetic material is not in a nucleus. Instead it exists as a DNA loop in the cytoplasm |
| No plasmids | Plasmids present |
