Year 12 Biology: Identifying mitosis in garlic roots (March 2017)

In this lesson, A-level biology students were completing a practical to try and identify mitosis taking place in garlic roots. When a cell undergoes mitosis, it is actively growing and cells are dividing to achieve this. If the students used the correct skills, they could cut the garlic root at exactly the right time, treat it with chemicals and stain it to see the cells as they divide. Many students completed the practical but one student in particular (Robert Green) was able to follow the practical method so precisely that the microscope slide he produced was fantastic quality (see images below). It has some cells caught undergoing mitosis where you can actually identify the chromosomes dividing. The slide he made is better quality than some of the exemplar slides that were being used to teach the topic – we have kept his slide for future reference!
