Living Organisms
- Bacteria
  - Tiny
    - Smaller than animal, plat or protoctists
  - Unicellular
  - Different structure to other cells
    - Common shapes include spheres, rods and spirals
    - Complex cell wall
      - Made up of polysaccharides and proteins
    - No nucleus
      - Genetic material forms a circular loop in the cytoplasm
      - Plasmids
        Small extra circles of DNA
    - Some have slime capsules for protection or flagella for movement
  - Some contain chlorophyll
    - Can photosynthesise
  - Most feed on dead or other living organisms
- Viruses
  - All are paraistes
    - And can only reproduce inside the living cells of a host
  - Smaller than bacteria
    - Very simple
  - All natural viruses cause disease
    - Every type of living organism can be infected
    - Each type of virus causes one specific disease
      - And is adapted to infect one particular organism
        Flu, HIV, AIDS
  - Found in many different geometrical shapes
    - Core of genetic material
      - surrounded by a protein coat
    - Contain DNA or RNA
      - Not both
- Protoctists
  - Make their own food
    - Some by photosynthesis
      - Algea
    - Some feed on other organisms
      - Protozoa
  - Most are unicellular
    - But some are multicellular
      - Seaweeds
    - Chlorella
  - Dustbin Kingdom
    - Mixed group of organisms that don't fit into plants, animal or fungi
  - Some cause disease
    - Plasmodium causes malaria
  - Many are very small (microscopic)
    - But some are very large
      - Seaweeds

This mind map is well organised, detailed and makes good use of colour to separate the kingdoms. (The spelling of parasite needs correcting.) There is second mind map that covers the remaining Kingdoms that should be reviewed alongside this one. It should be noted that viruses are linked to the heading 'Living organisms". Scientists do not classify viruses in any of the five kingdoms and regard them as non-living and students are expected to know why this is.
