- - - - Prokaryotic (before nucleus) - doesn't have a nucleus
      - Cell wall
        
        Protects and keeps shape of the cell
        
        Made of polysaccharides and proteins
      - Cell membrane
        
        How they respire - infolding of the cell membrane
      - Loop of DNA
        
        Inside a single chromosome
      - Rings/plasmids
        
        Genetic material
        
        Spread of infection and drug resistance
        
        Very important uses in genetic engineering
      - Different shapes
        
        Can have flagella (singular flagellum)
        
        Spirals
        
        Rods - longer rectangular shape
        
        Cocci - circular
      - Some have a capsule/slime layer
        
        Gives bacteria extra protection
      - Cytoplasm
  - - - Organic surface to grow from (can be dead or alive)
      - Hyphae (root like structures)
        
        Whole network called a mycelium
      - Fruiting body
      - Cell wall
        
        Made of CHITIN
      - Gills with spores
      - Cytoplasm within the hyphae
    - - Thrush
      - Athletes foot
  - - - Obligate intracellular parasite
      - Protein coat/caspid
      - DNA/RNA
      - Other chemicals
      - No nucleus
      - Not living
      - No cytoplasm
    - - Meningitis
      - Rubella
      - Mumps
      - HIV
      - Hepatitis A,B,C
      - Measles
      - Flu
  - - - Plasmodium - agent of malaria disease
    - - Most are unicellular, but some species such as seaweed are multi-cellular
