Starting with an explanation that our skin regenerates constantly using cell division, the process of cell division by mitosis and meiosis is demonstrated. Mitosis produces diploid cells and meiosis produces haploid sex cells. Both processes are described thoroughly and computer graphics are used to show what happens to the chromosomes during this process. The purpose of both processes is explained.
This could be used as an introduction to both mitosis and meiosis. It could be shown at the beginning of the topic to introduce the differences to students or at the end to review them. The clear computer graphics and precise voiceover explain this difficult process.
