![]() Hold the slide of the onion root up to the light and note that there are several longitudinal sections on the slide.While technically not a phase of mitosis, you may use “interphase” for some of the cells, but you should not use “cytokinesis.” The cells go in the appropriate temporal sequence through cell cycle and you are likely to use the same term multiple times. In Figure 5 below, identify the phase of mitosis and write the name of the phase below each diagram.In this exercise, we will consider prometaphase a component of prophase. You may find that some accounts of mitosis further subdivide the process to include prometaphase between prophase and metaphase. Mitosis is commonly divided into four major phases: prophase, metaphase, anaphase, and telophase. ![]() While the process of mitosis is continuous process within the cell cycle (i.e., it doesn’t occur in discrete steps), biologists are classifiers and tend to place things into discrete categories. Meiosis is another form of cell division in eukaryotes that leads to the production of gametes. Mitotic cell division is used in asexual reproduction, growth, and repair. Mitotic cell division leads to the production of genetically identical daughter cells from existing parent cells. ![]() Mitosis without the co-occurance of cytokinesis leads to the production of multinucleated cells, such as those found naturally in skeletal muscle and cardiac muscle. In eukaryotes, this generally occurs by the process of mitotic cell division, which involves the separate but often coordinated processes of cytokinesis (division of the cytoplasm and organelles) and mitosis (division of the nucleus and associated DNA). \)Īccording to the cell theory of biology, all cells arise from pre-existing cells.
