  • Living organisms
    • the biological system
      • arthropod- an important group of invertebrates.
        • an animal without a backbone
        • binomial- classification for each organism and species
        • cladistic- classification of each organisms common characteristics
        • DNA- carries genetic information
        • gills- the respiratory organ found in fish
          • have a large surface area and good blood supply for gas exchange in water.
        • parasite- an organism that lives in another organism (the host)
          • eg. a flea on a dog
        • species- a type of organism that is the basic unit of classification
    • chitin- hard and tough material made from glucose molecules.
      • chloroplasts- contains green pigment chlorophyll used in photosynthesis
        • chromosomes-structure of DNA which codes fro characteristics
      • dry mass- mass of an organism after water has been removed
      • glycogen- animals store glucose as glycogen in their muscles tissue and liver
        • pathogen- microorganism that causes disease
      • plasmid- small circles of genetic material that is used in cells in genetic modification
        • =altered of certain characteristics
      • startch- a type of carbohydrate
        • plants turn glucose into starch for storage (in photosynthesis)
          • they turn it back into glucose for respiration
      • Vacuole - a space where plants store cell sap
