This week we are starting Chapter 4: Cell Division. On Friday we watched a Clickview video showing the process of cytokinesis and mitosis, which included a discussion with a cancer surgeon about the types of treatments (chemotherapy and radiation) used to prevent cells dividing and multiplying, as they do in tumours. All living organisms undergo cell division – in unicellular organisms (such as bacteria and yeast) it is how they reproduce. In multicellular organisms, cells divide and multiply for growth, repair and maintenance.
Certain tissues, such as root tips and bone marrow, actively grow and divide and it is relatively easy to find cells undergoing mitosis. We will look at some prepared slides to see the different stages of mitosis – prophase, metaphase, anaphase and telophase – and cells in which the chromatin is not visible (interphase).
