| Outline |
| The bacteria cell: Cell shapes-Some bacteria look like little ball while others appear like tangled strings or corkscrews. Cell structures: Look at the picture below for some structure. |
 |
| The kingdomes of bacteria: Archeabacteria- or ancient bacteria, they live in the intestines of animals or in swamps. Sometimes they even produce foul oders Eurobacteria- Eurobacteria do not live in extreme envirorments. Most eurobacteria are useful or harmless to human bodies. |
 |
| Reproduction or bacteria: Asexual reproduction- This reproductive system only includes one parent to be completes. In binary Fission the parent duplicates its genetic material Identical to the parents. Sexual reproduction- In this system the two parents combine their genetic material to form a completly different bacterium. |
| Survival needs: Obtaining food- Some bacteria are autotrouphs and use the energy form the sun. Other autotrouphs live in the deeep ocean and use chemicals. Hetretrouphs eat both kinds of bacteria. Respiration- Some bacteria break down food, this proces is called respiration. This sometimes creates methane. |
 |
| Bacteria and the Living world: Food- Baacteria create some of the healthiest foods for example they create Yogart, sour cream, pickles and more. They put the sour in sour cream and bacteria that grow in the liquid poured on cucumbers create pickles. Envirormental recycling- Bacteria that live in soil decompose the large chemicals in dead organisms into a reusable form of living space for animals. Enviromental clean-up- Bacteria also help clean up old waste formed by chemicals. Health and medicine: Bacteria can be grown in labs and new bacteria are being used to fight against antibiotic resistence. . |
