  • Cell Specialisation
    • Sperm Cell
      • flagellum for swimming
      • many mitochondria
      • an acrosme containing enzymes to digest way into female gamete
    • guard cell
      • unevenly thickened walls so cells bend when turgid
    • combinations of cells each contribute their specific adaptations to the function of the organ
    • in multi-cellular organisms, specific groups of cells are specialized for a particular role. This increased efficiency helps the organism to have better survival qualities in the environment
    • system
      • a range of tissues and organs
    • organ
      • a collection of tissues which combine their properties for a specific function
    • tissue
      • a collection of similar cells, from the same source, all working together towards a particular function
    • red blood cell
      • contains haemoglobin
      • no nucleus, high SA
    • white blood cells
      • can surround foreign cells and debris
      • produces enzymes to digest foreign materials
    • epithelial cell
      • allows exchange of chemicals
      • very thin
    • plant palisade cell
      • contains chloroplasts
      • chloroplasts can move to reach light
      • contains chlorophyll to absorb light
      • sap vacuole contains important chemicals
  • Root Hair Cell
    • aim to increase surface area
