Mitosis

Cell Division


Mitosis1

Mitosis

  • Mitosis is the process of cell division producing identical daughter cells from the parent cell.

  • Used by single cell organisms to reproduce.

  • Asexual reproduction in organisms that “clone” to reproduce.


Mitosis

  • Multicellular organisms use mitosis to:

  • Grow, repair and replace worn-out or damaged cells.

  • Mitosis has 4 distinct phases;

    • Prophase

    • Metaphase

    • Anaphase

    • Telophase


Interphase

Interphase

  • The normal life cycle of the cell.

  • The Chromatin is duplicated.

  • Makes new organelles

  • Chromosomes are not visible yet.


Prophase the starting of mitosis

Prophase- The starting of Mitosis

  • First stage of Mitosis.

  • Sister chromatids become visible.

  • Centriloes move to poles of cell.

  • By end the end the nucleolus disappears.

  • Sister chromatid attach to spindle fibres.


Metaphase second stage

Metaphase- Second Stage

  • Sister chromatids attach completely attach to fibres.

  • Chromatids line up in the center.


Anaphase third stage

Anaphase- Third stage

  • Sister chromatids separate to become individual chromosomes.

  • Once chromosomes are at opposite ends of the cell Anaphase is over.


Telophase final stage

Telophase- Final Stage

  • Chromosomes uncoil and become chromatin again.

  • Spindle fibres disappear.

  • Nuclear envelopes develop.


Cytokinesis two new cells

Cytokinesis- two new cells

  • Cytokinesis is the formal splitting of cells.

  • Cell membrane pinches in to form 2 cells.

  • Usually happens the same time as telophase.
