Electron microscope
- Uses a beam of electrons to magnify specimens x 2,000,000
- Produces very clear images
- Helps us discover the detailed structure of cells
- Bacteria doesn't have nuclei
Bacterial cells
- Contain two types of DNA; Plasmid DNA & Chromosomal DNA
- Plasmid DNA comes in small loops and carries extra information
- Chromosomal DNA is a giant loop of DNA containing most genetic material
- Plasmid DNA comes in small loops and carries extra information
- Has a cell wall but is different to plants
- More flexible and is not made of cellulose
- Contains flagella on outside of cell
- Whip-like structure that bacteria use to carry themselves along
- Not all bacteria contain flagella
- Whip-like structure that bacteria use to carry themselves along
- Contain two types of DNA; Plasmid DNA & Chromosomal DNA
