Mitosis Cell Division Cell Division is the division of a cell into two daughter cells with the same genetic material.

Cell Division Living cells store critical information in DNA. As a cell grows, that information is used to build the molecules needed for cell growth. As size increases, the demands on that information grow as well. If a cell were to grow without limit, an “information crisis” would occur.

Cell Division There are two types of Cell Division Mitosis Meiosis

Cell Division Mitosis (Asexual) is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth https://www.youtube.com/watch?v=22V73bs4FAo

Important Cell Structures Involved in Mitosis Chromosomes – DNA in the shape of an “X” Chromatid – each strand of a duplicated chromosome Centromere – the area where each pair of chromatids is joined

Important Cell Structures Involved in Mitosis Centrioles – tiny structures located in the cytoplasm of animal cells that help organize the spindle Spindle – a fanlike microtubule structure that helps separate the chromatids

Cell Division Mitosis

Cell Division Prophase Metaphase Anaphase Telophase Cytokinesis Stages of Mitosis Prophase Metaphase Anaphase   Telophase Cytokinesis

Cell Division Prophase - the chromosomes become visible as paired chromatids and the nuclear envelope disappears

Cell Division Metaphase - the chromosomes become attached to the spindle fibers.

Cell Division Anaphase  - the chromosomes move away from one another to opposite poles of the spindle.

Cell Division Telophase - the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed

Cell Division Cytokinesis - is the separation into two daughter cells.
