  • taxonomy?

    process of placing organisms into groups based on their shared features
  • 5 kingdoms?
    • animalia
    • fungi
    • plantae
    • prokaryotae
    • protocista
  • animalia? (kingdom)
    • multicellular eukaryote with differentiated cells organised into specialised organs.
    • no cell wall/ vacuole and cannot photosynthesise
    • heterotrophic, rely on other organisms for nutrition
    • most can move from place to place
    • includes phyla like jellyfish, roundworms ect
  • fungi?
    • multicellular eukaryotes with differentiated cells, yeast included are unicellular
    • cell walls made of polysaccharide chitin
    • cannot photosynthesise
    • heterotrophic, most absorb nutrients from decaying matter after digestion
    • most made up of network of thread-like strands
    • includes mould yeast mushrooms
  • plantae?
    • multicellular eukaryotes with differentiated cells organised into specialised organs
    • cell walls contain cellulose
    • cells contain chloroplasts/vacuole
    • make organic compounds via photosynthesis
    • includes mosses, ferns, conifers
  • prokaryotae?
    • cells small, less than 10micrometers
    • cells have no distinct nucleus, nucleic acid is single chromosome
    • cells dont have organelles, mitochondria/chloroplasts
    • includes bacteria
  • protocista?
    • multicellular/unicellular eukaryotes
    • basic body structure is simple
    • may either photosynthesise or feed on organic matter from other sources
    • includes amoeba and algae ect
  • further classification
    K, kingdom
    P, phylum
    C, class
    O, order
    F, family
    G, genus
    S, species
  • molecular phenology?

    study of evolutionary relations among groups of organisms by analysing hereditary molecular differences in DNA/RNA sequences
    • identification of 3 domains, classification is dynamic (constant new available data)
