    • Characteristic of living things
      • NUTRITION
      • RESPIRE
      • EXCRETE WASTE
      • RESPONSE TO THEI AREA AROUND THEM
      • MOVEMENT
      • CONTROL INTERNAL CONDITIONS
      • REPRODUCE
      • GROW AND DEVELOP
    • VARIETY OF LIVING ORGANISMS
      • plants
        • Multicellular
        • Cells contain chloroplasts + can P/S
        • cellulose cell walls
        • store carbs as starch and sucrose
        • FLOWERING PLANTS
      • Animals
        • multiceluular
        • dont contain chloroplasts
        • no cell walls //Nervous Coordination
        • store carbs as glycogen
        • MAMMALS
      • Fungi
        • not able to P/s
        • bodies made from   thread like structures called HYPHAI
          • MUCUR
        • contain lots of nuclei
        • cells made out of chitin
        • feed by extravellular secretion of digestive enzymes
          • absorption of organic products= Saprotrophic nutrition
        • store carbs as glycogen
        • some single celled
          • YEAST
      • Bacteria
        • microscopic single-celledorganisms
        • cell wall, cell membrane, cytoplasm, ++ plasmids
        • no nucleus butcontain circular   chromosomes of DNA
        • some p/s
        • feed off living or dead material
        • LACTOBACILLUS BULAGRICUS ROD SHAPED BACTERIUM
      • Protoctists
        • microscopic single celled
        • AMOEBA>live in pond like animal cell
        • CHLORELLA> chloroplasts more like plants
        • PLASMODIUM > responsible for malaria
