Cell Division Why do we need cell division?

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

What is cell division? Cell division is when a parent cell divides to produce two identical daughter cells

What do we need cell division for? On your white boards write down as many things as you can think of that would require cell division

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

Cell division - the bad Uncontrolled cell division causes cancer What Is Cancer? : Twig

Your 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

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 is necessary How cell division is important to your chosen aspect
