Functions of major parts
- DNA: Contains genetic information for the bacteria. Controls all the chemical reactions within the cytoplasm.
- Capsule: Protects bacteria from heat and chemicals
- Flagellum: For movement.
- Fimbriae/Pilli: For attachment (eg. on the surface of stomach)
- Cell wall: Maintains the shape of the bacteria.
- Ribosomes: For making protein.
- Cytoplasm: This is where all the chemical reaction happens (including making proteins).
- Plasma-membrane/ cell membrane: Controls what comes in and goes out.

- A bacterium breaks down the organic fertilizer (decomposed vegetables and animal matter) into material that can be used by plants.
- Some species of soil bacteria convert nitrogen into nitrites, compounds that are readily absorbed by plants.
- Different commercial processes also need certain bacteria, like Anaerobic bacteria that ferment certain substances are used in the production of vinegar and some drugs, and in the aging process of cheeses.
