The Cell Cycle

Tennessee State Standards Addressed • Grade 7 • GLE 0707. 1. 4 Illustrate how cell division occurs in sequential stages to maintain the chromosome number of a species. • SPI 0707. 1. 4 Sequence a series of diagrams that depict chromosome movement during plant cell division.

Interphase Cytokinesis Mitosis Click on a green box to learn more Take about that stage of the cell cycle Quiz

Interphase • During Interphase, the cell’s chromosomes duplicate. • This is the phase that occurs BEFORE mitosis begins. • A period of Growth Take Quiz

• Mitosis is the part the cell cycle in which the NUCLEUS divides • There are 4 phases of Mitosis… – Prophase – Metaphase – Anaphase – Telophase – Or…PMAT

Prophase • Prophase is the FIRST phase of Mitosis • The nuclear membrane has disappeared • Chromosomes have condensed and shortened • Centrioles move to opposite ends of the cell (in Animal cells ONLY) • Plant cells do NOT have Centrioles

Metaphase • Metaphase is the Second phase of Mitosis • Chromatids line up in the MIDDLE of the cell • Spindle fibers attach to the Centromeres

Anaphase • Anaphase is the THIRD phase of Mitosis • Each pair of chromatids separate, because the spindle fibers begin to shorten • The separated chromatids are now called chromosomes

Telophase • Telophase is the LAST phase of Mitosis • TWO NEW NUCLEI form, but the two new cells are still connected • Spindle fibers start to disappear • In plants, a cell plate forms between the two new cells

Cytokinesis • Cytokinesis occurs after the last phase of Mitosis • The CYTOPLASM separates and two new cells form • In plants, new Cell Membranes form from the Cell Plate Take Quiz

That is CORRECT! Great Job!
