| Question | Answer |
| What are three Different types of microbe? | Bacteria,Viruses,fungi |
| Bacteria ? | Eg salmomella Shape - Spherical,Rod,Comma Structure- single celled Reproduction - They double very quickly |
| Viruses? | e.g. flu virus shape: Viruses have regular and geometric shapes. structure: A virus is a simple organism which does not display ALL the characteristics of living things. They are made up of a protein coating and some genetic material. reproduction: Viruses can only grow and reproduce within other living things. |
| Fungi? | e.g. Penicillium size: Some fungi can actually be seen with the naked eye, others are slightly bigger than bacterial cells. shape: Fungi come in many different shapes. structure: Fungi have the most complex structures of all the microbes. They feed off other living things. |
| How do microbes spread through air? | A cough or a sneeze can release millions of microbes into the air which can then infect somebody else |
| How do microbes spread Transmission by water? | Dirty water can transmit many diseases, e.g. cholera, which can be transmitted by drinking. |
| How do microbes spread by animals? | An animal can carry a microbe from one place to another, e.g. a mosquito which spreads the malaria parasite |
| How do microbe spread through contact? | Many microbes can be exchanged from one person to another by direct or indirect contact: direct contact by hand; indirect contact, e.g. by walking on a wet floor already contaminated by someone else who has athlete’s foot; |
| How is the spread of disease stopped? | The spread of disease can be prevented by making sure that good hygiene is used in key places such as bathrooms and kitchens. Chemicals called antibiotics can be used to treat bacterial infections. People can be immunized against some diseases by the injection of a vaccine. |
| What do white blood cells do? | Some white blood cells can destroy microbes by engulfing them. Some white blood cells are able to produce chemicals called antibodies. These pairing with matching antigens on the surfaces of microbes and so help the white blood cells to engulf microbes. |
| antibiotics | – Chemicals prescribed as medicine to kill bacteria inside the body. |
| antibodies | Chemicals produced by white blood cells to fight microbes that cause disease |
| bacteria | The type of microbes that are single-celled organisms. |
| fungi | The type of microbes that feed off other living things. |
| immune | Resistance to infection caused by a microbe. |
| microbe | A very small living thing. |
| transmission | The spread of a disease from person to person. |
| viruses | The type of microbes that can only grow and reproduce within other living things. |
| Where can microbes exeter the body? | They can be breathed in through the mouth or nose They can be ingested (eaten) through the mouth They can enter through cuts or bites in the skin or just by touching something |
| Natural defences? | Skin Platelets Stomach acid Tears Mucus |
