Cell division teaching resources

Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about mitosis and meiosis (GCSE and Key Stage 3)

Overview: it’s strange to think that once upon a time we were all just one cell. Cell division enables organisms to grow, replace damaged tissue and reproduce. Mitosis is the cell division associated with growth and asexual reproduction. One parent cell splits into two daughter cells following the replication (duplication) of the genetic material inside the nucleus. The daughter cells produced my mitosis are identical to the parent except for any mutation that has taken place. Meiosis in contrast is the cell division associated with sexual reproduction. Here, one parent cell forms four haploid gametes, each containing half the amount of genetic information as their parent. Importantly, meiosis produces daughter cells that are different from each other and the parent cell – it introduces variation. Cancer is a disease caused by uncontrolled cell division – it’s when mitosis goes wrong. Many drugs that target cancer cells also target cells that divide  – that’s one of the reasons for hair dropping out during chemotherapy. 

Key concept: cell division allows organisms to grow, replace damaged tissue and reproduce. When cell division is uncontrolled we get important human diseases such as cancer.

Prior knowledge: cell structure, chromosomes and genetic organisation inside the nucleus 

This excellent video shows a fertilised human egg undergoing its first few mitotic divisions.

 


Teaching resources

Cell division for growth and repairMitosis and general cell division

Key Stage 3 worksheet to identify when cell division occurs. Students are given a series of pictures. They identify whether cell division has taken place. This is a great starting point to introduce mitosis.

Meiosis

A Level activity on the stages of meiosis. This resource can be used to help students recognise the different meiotic stages. Students are shown pictures of cells undergoing meiosis. They must identify each meiotic stage and put the images in the correct order. (PDF)

Videos of cell division

A fantastic collection of videos and images of cells provided by The Cell. These videos are freely available and can be used to show students the dynamic nature of cells division.
