Slide 3

    Viruses are not cells. They live inside cells and reproduce rapidly, until the cell bursts. Viruses escape through the airways and bloodstream and can spread through populations. The cell damage is what causes you to feel ill. Common examples of illnesses caused by viruses are: - Flu - Measles - Mumps - Common cold - AIDs
    Viruses

Slide 4

    Some fungi are single celled while others have a body made up of hyphae (thread like structures). Hyphae can grow and penetrate human skin and the surface of plants, causing diseases. The hyphae can produce spores which can be spread to other plants and animals. The most common fungal infection a human can get is athletes foot.
    Funghi

Slide 5

    Protists are single celled eukaryotics. Some protists are parisites. Parasites live on or inside other organisms and can cause them damage. They are often transferred to the organism by a vector e.g. an instect that carries the protist. An emaple of this is malaria. The protist lives in the bloodstream and is tranferred by mosquitos.
