Topic 5 (Diseases they cause (Fungi (Characteristics of fungi (Hyphae…

- - - - Hyphae which plant themselves into the object
      - Grow on organic material, either dead or alive
      - Gills with spores which create more fungi elsewhere
      - Cell wall made of CHITIN
      - Fruiting body grows above surface
      - Cytoplasm
    - - Thrush
      - Potato blight
      - Athletes foot
  - - - Prokaryotic
        
        'Before nucleus' (doesn't have a nucleus)
      - Shapes of a bacteria
        
        Cocci (round)
        
        Ralo - Bacilli (long rectangular shape)
        
        Spirals
        
        Flagella
      - Loop of DNA
      - Cell wall
      - Rings/plasmids
        
        Genetic material
        
        Spread of infection and dry resistance
      - Cell membrane
    - - Salmonella
      - Gonorrhea
      - Meningitis
  - - - Obligate intracellular parasite
      - Protein coat/capsule/caspial
      - DNA/RNA
      - Other chemicals
      - No nucleus
      - Not living
    - - HIV
      - Flu
      - Rubella
      - Mumps
      - Hepatitis A, B, C
      - Measles
  - - - Single celled animal
      - Often grouped together for 'convenience'
    - - Malaria
- - - - Bacterial species that infects a number of plant hosts
      - What do they attack?
        
        Delphinium flowering plants
        
        Celery
        
        Primulas
        
        Cucumbers
        
        Snapdragons
        
        Plums
  - - - Caused by the fungus Diplocarpon rosae
      - Infects the leaves of many roses
      - Marks the leaves of infected plants much like the Tobacco Mosaic Virus, turning them purple or black
        
        Reduces ability for the plant to photosynthesize and get the glucose needed for life processes
        
        Heavily marked leaves will die and drop from the plant
      - Spread is prevented by burning all infected leaves and stems after they have been removed from the plant
  - - - It causes the leaves of infected plants to have discoloured patterns (resembling mosaics)
        
        This reduces the ability for that plant to photosynthesize and therefore produce the glucose it needs to grow
      - It's a common pathogen of many plants including tobacco and tomato plants
      - Particularly good at surviving without a host if the temperature of it's environments stays below 40 degrees Celsius
      - Can remain in the soil and infect other plants planted there
      - It costs an estimated loss of $60 billion a year (US)
- - - - Virus
      - Fungi
      - Bacteria
      - Protista
