1. Fungi have a nucleus, a cell wall and are bigger than bacteria. Fungi can grow long hyphae, bacteria divide in two.

2. Viruses need to invade the cells of other living things to reproduce.

3. Antibodies are proteins made by white blood cells. They stick to particular microbes and clump them together.

4. White blood cells make antibodies and destroy microbes. Without them we have no immunity from infectious diseases.

5. The bacteria in TB vaccine are killed and so will not cause disease. White blood cells that recognise TB respond to the bacteria and destroy it. Some of these remain in the blood so that the next time TB bacteria invade your body they are immediately destroyed.

6. The Chinese learned how to inoculate with smallpox matter (sixteenth century)

Lady Mary Wortley Montagu brought inoculation to England (1721)
Edward Jenner invented vaccination with cowpox (1796)
The WHO campaign eradicated smallpox (1960-1980)

8. Provide water, warmth, food and oxygen. Test for carbon dioxide production and look for the growth of colonies.
You should protect yourself by sealing the experiments and destroying any material by burning it.
