Lily mitosis. A light microscope image of a cell from the endosperm of an African globe lily Haemanthus (Scadoxus) katherinae. This is one frame of a sequence that shows all phases of mitosis. The lily is considered a good organism for studying cell division because its endosperm has a liquid phase and chromosomes are thick and easier to see than human ones. Staining shows microtubules in red and chromosomes in blue. This image showing a cell approaching metaphase is the 5th of a grouped series that spans mitosis.
