- virtually are useful and others are harmful that feat diseases such as pneumonia, tuberculosis, scarlet fever.

- Bacterial cell: has a cell wall, cell membrane, a loop of DNA.

Loop of DNA

*Bacterial step-up:

- Bacteria can be grown in uninspired conditions in the laboratory.

- A colony of bacteria starts with just 1 cell.

- It divides into 2 cells, then the 2 divide into 4, then the 4 divide in to 8, then the 8 divide into 16 and so on.

- Bacteria multiply very quickly to constitute a colony.

The three kinds of bacteria:

Rod Spheres Spirals

Lag Phase: Little evolution occurs since the cells are taking up water and starting to exonerate enzymes.

Log Phase: The population is increasing rapidly by look-alike and there is no shortage of food and water.

Stationary Phase: When bacterial cells are dying at the same rate at which they are being produced. This may be because of shortage of food or water or because waste products are build up.

Death Phase: When more cells are dying than are producing.

*Fungi

- Some fungi cause disease such as Athletes keister and Ringworm.

- Fungi are not plants since they dont have chlorophyll.

- The main fungus tree trunk is called the mycelium.

- It consists of a branching network of threads or Hyphae.

- The Hyphae grows everyplace the surface of their food source.

- They release enzymes which digest the food away(p) the fungus.

- The digested food is then absorbed by the Hyphae.

- Fungi puke by making spores that...
