fungal and protists disease

• Fungi


  Eukaryotic organisms, can be unicellular or multicellular
• Fungi


  • Yeast
  • Mushrooms
• Multicellular fungi


  • Have long thread-like structures called hyphae which come out of the main body and spread through the soil
• Fungal disease spread


  1. Hyphae spread over plants or even penetrate human skin

  2. Hyphae produce spores which spread easily and grow into new fungi
• Fungal disease


  • Rose black spot
• Rose black spot


  • Causes purple or black spots to form on the leaves of plants, especially roses
  • As the fungus does more damage, the leaves can start to turn yellow and drop off
• Treating rose black spot

  1. Chop off all infected leaves and destroy them

  2. Spray the plant with fungicides
• Protists


  Eukaryotic organisms, can be single-celled or multi-celled
• Protists


  • Large majority are single-celled or unicellular
  • Some are classed as parasites which means they live on or inside other organisms and survive at that other organism's expense
• Vectors


  Other organisms like insects that transport protists between different host organisms
• Protist disease


  • Malaria
• Malaria transmission


  1. Mosquito feeds on infected animal and sucks up malaria parasites

  2. Mosquito then transfers parasites to healthy person when it feeds on them
• Malaria


  • Causes recurrent episodes of severe fever and headaches in humans
  • Can be fatal in some cases
• Preventing protist diseases


  1. Reduce number of vectors (e.g. mosquitoes) by destroying breeding sites or killing them with insecticides

  2. Stop vectors from feeding on humans by using mosquito nets or repellents
