| Question | Answer |
|---|---|
| A type of microbe bigger than viruses. | bacterium |
| Organisms which are different from animals, plants and bacteria. | fungus |
| A very small living thing. | micro-organism |
| A living thing. | organism |
| The smallest type of microbe. | virus |
| A type of fungus with only one cell and therefore a microbe. | yeast |
| A type of respiration that needs oxygen. | aerobic respiration |
| A type of respiration that does not need oxygen. | anaerobic respiration |
| The way yeast cells divide. | budding |
| Often just called ‘alcohol’. Produced by yeast when they ferment sugar. | ethanol |
| The type of anaerobic respiration carried out by yeast. | fermentation |
| Something that stops a population growing. | limiting factor |
| The numbers of a certain organism found in a certain area. | population |
| When some processes that happen in the body do not work in the way they should. | disease |
| Information that helps to prove that an idea is correct. | evidence |
| A high body temperature. | fever |
| When a microbe gets into your body. | infect/infection |
| A disease that can be spread from person to person or from animal to person is.. | infectious |
| Looking carefully at things and recording what you see or measure. | observation |
| An idea about what will happen when you change something. | prediction |
| The effects that a disease has on your body. | symptoms |
| A scientific idea that can be tested. | theory |
| Small chemicals made by some white blood cells. They attach to microbes and help to destroy them. | antibody |
| Weak disinfectant safe to use on human skin. | antiseptic |
| Cells in the trachea which have microscopic hairs | ciliated epithelial cells |
| When blood becomes solid. | clot |
| Strong chemical used to kill microbes. | disinfectant |
| When a white blood cell completely surrounds a microbe and destroys it, it is said to engulf the microbe. | engulf |
| Sticky substance used to trap microbes and dust. Found in nose and trachea. | mucus |
| Your body’s way of trying to keep microbes out (e.g. skin) or killing them if they get inside you (eg stomach acid). | natural defences |

| A dry blood clot on the surface of the skin. | scab |
| Another name for the windpipe. | trachea |
| A type of blood cell which helps to destroy microbes. They either engulf microbes or make antibodies. | white blood cell |

| If you cannot get a disease you are said to be ‘immune’ to it. | immune |
| Making people immune to diseases. | immunisation |
| A drug that helps the body to ease the symptoms of a disease or cure the disease. | medicine |
