Mitosis. False-colour scanning electron micrograph of a cell from ovary tissue (centre) undergoing mitotic cell division. In mitosis a single cell produces two genetically identical daughter cells. The last stage of mitosis (telophase) is visible here. The two daughter cells are still connected by a narrow cytoplasmic bridge. At this stage chromosomes have already been duplicated and distributed to the daughter cells. Long filaments protrude from the cell surface. They supply the cell with nutrient substances from the surrounding environment and provide mechanical support. Magnification: x1070 at 6x7cm size.
