- - - - reduced mitochondria hydrogen by-product
  - - - single large mitochondrion
        
        kinetoplast
        
        organized mass DNA
      - feed on prokaryotes aquatic/terrestrial
      - parasites
        
        Ex: Trypanosoma=sleeping sickness
    - - pocket end cell
      - 1/2 flagella
      - mixotrops
      - hetertrophs:phagocytosis
- - - - cellulose plates
      - 2 flagella
      - "red tide" in Australia
      - carotenoid pigments in plastids
    - - parasites of animals
      - sporozites
        
        tiny cell
        
        infectious
        
        spread in host
      - Apical complex
        
        end of cell
        
        organelles
        
        penetrate host
      - Plasmodium=maria
    - - motile
      - with cilia
      - micro and macronuclei
      - Paramecium
  - - - porous shells=tests
      - foram fossils
    - - delicate skeletons,silica
      - symmetrical
      - pseudopods radiate from center
    - - amoeboids
