  1. National 4/5 Biology Section 3 Cell Division Why do we need cell division?

  2. Recap • Using the cards provided sort the stages of cell division into order with matching statements

  3. What are we learning today? • We are learning to: - explain why cell division is essential for living organisms - explain what happens when cell division occurs uncontrollably • Success criteria: - cell division essential for growth - cell division is essential for repair of damaged tissue e.g. broken bones and cuts - cancer occurs as a result of uncontrolled cell division

  4. Cell division is essential for growth From this oak tree sapling To this mighty oak tree

  5. Cell division – the good • Cell division enables damaged tissues to mend • For example:

  6. Cell division - the bad • Uncontrolled cell division causes cancer

  7. You task • Choose an aspect of cell division - regeneration of tissue in Salamander - regeneration of tissue in starfish - wound healing - healing of broken bones - uncontrollable cell division • Investigate it and create a presentation, poster, information booklet

  8. Presentation should include • Title • Introduction – why you chose it and what it is about • Back ground knowledge of what cell division is and how it works • Why cell division necessary • How cell division is important to your chosen aspect
