  • Classification
    • Kingdoms
      • Prokaryotae
        • Unicellular organisms like blue-green algae and bacteria
        • They have internal cell membranes and so no ERs, nuclear membrane, golgi body ETC
        • They have a cell wall but it isn't made of cellulose
      • Protoctista
        • Mostly small eukaryotic organisms that didn't fit anywhere else.
        • They have membrane bound organelles like a nucleus
      • Fungi
        • They are made of a network of fibers called hyphe and then these come together to make mycelium
        • Cell wall is made of chitin
        • They have no photosynthetic tissues and feed hetrotorphiclly, so they feed on other things
        • They reproduce via spores
      • Plantae
        • These are plants.... They are larger multicelluar organisms that produce sugar via photosynthysis
        • The cells are plant cells, with a cell wall, a vacuole containing cell sap and chloroplasts filled with chlorophyll to photosynthyse
      • Animals
        • Advanced multicellular organisms that are hetrotophic as well as lacking a cell wall
        • Have a nervous system
        • It consists of two main groups, chordates and non-chordates (vertebrates and invertebrates)
          • segmented worms etc are non-chordates and fish and reptiles are chordates
    • Levels of classification
      • Kingdom
        • The largest grouping, e.g. plants and animals
      • Phylum
        • Groping of classes that share common features
      • Class
        • A grouping of similar orders, e.g. Insecta
      • Order
        • Grouping of similar famlies e.g. orthoptera, consisting of locusts and crickets
      • Family
        • A grouping of similar genera (plural genus)
      • Genus
        • A group of species that are very closely related e.g. Locusta
      • Species
        • A group of species that share a large number of common characteristics and can successfully interbreed to produce fertile offspring
      • ***** Prostitutes Can Offer Fantastic *********
      • A taxon is  a level of classification
    • Ordering different animals into manageable groups
    • Taxonomy is the study of the diversity of living organisms and these are the people who group species
    • You develop the name of an animal based on it's generic name (Genus) and its specific name (Species) and the international language for this is latin
