    • What are the two types of eukaryotic cells?
      Animal and plant
    • What type of cell are bacteria?
      Prokaryotic
    • Where is DNA found in animal and plant cells?
      In the nucleus
    • What is the function of the cell membrane?
      Controls movement of substances in and out of the cell
    • What is the function of mitochondria
      Site of respiration to transfer energy for the cell
    • What is the function of chloroplasts?
      Contain chlorophyll to absorb light energy for photosynthesis
    • What is the function of ribosomes?
      Enable production of proteins
    • What is the function of the cell wall? 

      Strengthens and supports the cell
    • What is the structure of the main genetic material in a prokaryotic cell?
      Single loop of DNA
    • How are electron microscopes different to light microscopes?
      Electron microscopes use beams of electrons instead of light, cannot be used to view living samples, are much more expensive, and have a much higher magnification and resolution
    • What is the function of a red blood cell?
      Carries oxygen around the body
    • Give three adaptations of a red blood cell
      no nucleus, contains a red pigment called haemoglobin, and has a bi-con cave disc shape
    • What is the function of a nerve cell?
      Carries electrical impulses around the body
    • Give two adaptations of a nerve cell
      Branched endings, myelin sheath insulate the axon
    • What is the function of a sperm cell?
      Fertilises an ovum
    • Give two adaptations of a sperm cell
      Tail, contains lots of mitochondria
    • What is the function of a palisade cell?
      Carries out photosynthesis in a leaf
    • Give two adaptations of a palisade cell?
      Lots of chloroplasts, located at the top surface of the leaf
    • What is the function of a root hair cell?
      Absorbs minerals and water from the soil
    • Give two adaptations of a root hair cell
      Long projection, lots of mitochondria
