Key Points: Prokaryotic Cells
- Prokaryotes include bacteria, blue-green algae, mycoplasma and PPLO. They are generally smaller and multiply faster than eukaryotic cells.
- Most prokaryotes have a cell wall, except mycoplasma. They lack a well-defined nucleus as genetic material is not enclosed by a nuclear membrane.
- Four basic shapes of bacteria: bacillus (rod-like), coccus (spherical), vibrio (comma-shaped) and spirillum (spiral).
- Many bacteria have plasmids, which are small circular DNA outside the main genomic DNA and can confer unique traits like antibiotic resistance.
- Prokaryotes lack membrane-bound organelles except ribosomes and have unique cell inclusions and mesosomes (infoldings of the cell membrane).
