Understanding the Cell Cycle: Stages and Processes of Mitosis

DESCRIPTION

The cell cycle encompasses the growth, preparation for division, and reproduction of cells. It is divided into distinct stages, including Interphase (where most cellular activity occurs, and chromosomes replicate), Prophase (where chromosomes become visible), Metaphase (chromosomes align in the center), Anaphase (sister chromatids separate), and Telophase (nuclear envelopes reform). Following mitosis, cytokinesis occurs, resulting in the division of the cytoplasm and the formation of two new cells, each equipped with its own nucleus.

Presentation Transcript

  1. The Cell Cycle Cells grow, prepares for division, divides, and begin cycle again.

  2. IPMAT Stages of the cell cycle • Interphase • Prophase • Metaphase • Anaphase • Telophase

  3. Interphase • Most of the cell’s life time. • Chromosomes replicate. • Chromosomes are not visible under microscope.

  4. Prophase • 1st stage of mitosis. • Chromosomes become visible through a microscope. • Nuclear envelope breaks down. • Chromosomes attach to spindle fibers.

  5. Metaphase • Chromosomes line up in center of cell. • Chromosomes connected to spindle fiber at its centromere.

  6. Anaphase • Sister chromatids separate and are pulled to opposite sides of the cell.

  7. Telophase • New nuclear envelopes are formed around each set of chromosomes.

  8. Cytokinesis • Cytoplasm pinches off to form two new cells, each with its own nucleus.
