Time lapse pictures of a cell undergoing mitosis. During mitosis, the chromosomes shorten and thicken to move around. Each chromosome is made up of two chromatids that line up along the equator of the cell before pulling apart. The cytoplasm then divides to form two identical cells.
The clip could be used as a clear demonstration of the mitosis process, forming part of a lesson on cells and their multiplication. It could also contribute to lessons on chromosomes. Students could put together their own slide show or animation that explains the process in their own words.
