Bacterial Cells
Bacterial cells are examples of prokaryotic cells. The sub-cellular structures found inside them include:
Cell wall and cell membrane
- Bacterial cells contain a cell membrane and a cell wall, which provides structure.
Cytoplasm
- Cytoplasm is a jelly-like fluid that fills the cell.
- The cytoplasm is where most of the cell’s chemical reactions take place.
Flagella
- Some bacteria have flagella.
- Flagella are whip-like structures used for movement.
Plasmids
- Plasmids are small rings of DNA.
