  • B1- Classification
    • Kingdoms
      • Plants
        • Animals
          • Fungi
            • Protoctists
              • Prokaryotes
                • Unicellular, no nucleas
              • Unicellular, has nucleas
            • Saprophytes, multicellular, cell wall, no chlorophyll
          • Heterotrophs, multicellular, no cell wall or chlorophll
        • Chlorophyll, Autotrophs, Multicellular, Cell walls
      • Sub-divided into smaller groups. Organisms with common features
    • Kingdom  Phylum    Class    Order     Family   Genus Species
    • Animals
      • Vertabrates
        • Fish        Amphibians     reptiles        birds          mammals
          • Split into classes based on....
            • How they absorb oxygen (lungs, gills etc)
            • How the reproduce- Oviparous (lay eggs) Viviparous (live birth)
            • How they regulate body temperature- Homeotherm ( constant tempertaure0 Poikiotherm( changes with external heat.
      • Invertabrates
    • Organisms are the same species if the can interbreed to produce fertile offspring
      • However some species produce asexually
      • If two different species breed and produce offspring then this is called a hybrid. (e.g. Mallard with a yellow billed duck)
      • There is a lot of variation within a species. E.g. there are tons of breeds of dogs.
      • A ring species is a group of related populations that live in neighbouring areas.
        • Populations living next to each other can interbreed and produce fertile offspring. Ones that live further apart can't.
    • The binomial system gives each species a two part Latin name.
      • It helps scientist-  identify species, study species conserve species and target conservation efforts.
    • A key is a series of questions that can be used to identify an unknown organism.
