  1. Cells Division of Labour (Part 2)

  2. We are made up of trillion of cells… But are all our cells in our body the same?

  3. red blood cells Nerve cell Sperm cell Human egg cell White blood cell muscle cells

  4. Division of Labour Different types of cells are suited to perform different functions in the living organism This is called division of labour Think: Why is division of labour necessary?

  5. Division of Labour Division of labour increases the efficiency of the system Faster; less wastage of energy, time and materials Cells have special features or adaptations to help them perform their specific functions

  6. Division of labour Red Blood Cells • Function: transport oxygen from the lungs to all parts of the body • They are able to do this because they have a few adaptations. • Adaptations: • Contains a red pigment called haemoglobin which binds to oxygen to allow oxygen to be transported • NO nucleus (anucleated) so more haemoglobin can be packed into the cell to carry more oxygen

  7. Division of labour Root hair cells found in plants Function: absorption of water and mineral salts from the soil. Adaptation: has long narrow outgrowths to increase surface area for faster absorption

  8. Division of labour Palisade cellsfound in leaf of plants Function: Carry out photosynthesis Adaptation: Has numerous chloroplasts which contain the green pigmentchlorophyll to carry out photosynthesis.
