Hybrid Medical Animation - The Stages of Mitosis. Phases of Mitosis in Plant and Animal Cells. Cell Division Overview Clockwise, from top left: embryonic sea urchin cells, frog skin cells, neuron, 8-cell fish embryo. All of the living organisms on Earth are made up of one or more cells, which are the simplest units of life capable of independent existence and reproduction. Cells have the extraordinary ability to make nearly identical copies of themselves by the process of cell division. Since new cells are only produced by existing cells, cell division is essential for the continuation of life. There are a variety of reasons that might cause a cell to divide: Multicellular organisms grow in size and complexity by making more cells.
Two events are required for successful cell reproduction. The second requirement is the partitioning of cytoplasm between the two daughter cells. The Cell Cycle The orderly program of events in the lifetime of a cell is known as the cell cycle. The Phases of Mitosis Compare and contrast mitosis in the following plant and animal cell pictures: Prophase Anaphase. The Control of the Cell Cycle.
