  • Eukaryotic organisms


    Plants
    Animals
    Fungi
    Protoctists
  • Prokaryotic organisms 

    Bacteria
  • Plants
    Multicellular
    Store carbohydrates as starch or sucrose
    Have chloroplast therefore can photosynthesise
    Cellulose cell walls
    Cereal, Rose, Peas
  • Animals
    Multicellular
    Store carbohydrates as glycogen
    Cannot photosynthesise
    No cell walls
    Usually have nervous coordination that allows them to move from place to place
    Humans, Mosquito, Cats
  • Fungi
    Most are multicellular, some are unicellular
    Store carbohydrates as glycogen
    Cannot photosynthesise
    Body is usually organised in a mycelium structure made up of thread like structures called Hyphae (contains many nuclei)
    Chitin cell walls
    Saprotrophic - Extracellular secretion digestive enzymes (excrete enzymes outside of their body) onto food molecules and absorb organic material
    Mucor - typical fungal hyphal structure
    Yeast - Single-celled
  • Protoctists
    Microscopic unicellular
    Amoeba - live in pond water and have features like animals
    Chlorella- Have chloroplasts and have features like plants
    Plasmodium - Pathogenic, causes Malaria
  • Bacteria
    Microscopic unicellular organisms
    Peptidoglycan cell wall
    Cell membrane
    Plasmid
    Cytoplasm
    Lack nucleus - but have a singular circular chromosome of DNA
    Some can carry out photosynthesis
    Most feed off dead or living organisms
    Lactobacillus bulgaricus - Rod-shaped used in the production of yoghurt from milk
    Pneumococcus - Spherical, causes pneumonia
  • Virus
    Not living organisms
    Smaller than bacteria
    Parasitic, can only reproduce inside living organisms
    Infect every type of living organisms
    Wide variety of shapes and sizes
    No cellular structure, but have a protein coat
    Contain 1 type of nucleic acid (DNA or RNA)
    Tobacco mosaic virus - Causes discolouring of tobacco leaves by preventing formation of chloroplasts
    Influenza virus - Causes Flu
    HIV virus - AIDS
  • Pathogen

    Disease causing microorganism
