Mitosis
PHASES





Prophase
Metaphase
Anaphase
Telophase
Cytokinesis


Divided into four phases
The process can last as long as a few minutes
up to several days
PROPHASE





First and longest phase
50 to 60 percent
Visible chromosomes
Centriole separate and
spindle form
Nuclear membrane
breaks down
METAPHASE




Second phase
Last for a few minutes
Chromosomes line up
across the center
Centromere of each
chromosome are
connected to the spindle
poles
ANAPHASE




Centromeres that join
the sister chromatids
separate
Individual
chromosomes
Chromosomes
continues to move
Ends when
chromosomes stop
moving
TELOPHASE






Final phase
Re-form nuclear envelope
Spindle begins to break
apart
Nucleolus becomes visible
A new daughter cell is
born
Cell division is not
completed but mitosis is



Division of the cytoplasm
Contains its own nucleus and cytoplamic
organelles
Completes the M phase

Mitosis is cell division
Prophase is the first and longest phase
 Metaphase is when the chromosomes line up across
the center of the cell
 Anaphase is when the chromosomes separate
 Telophase is two nuclei is formed (daughter cells)

Cytokinesis divides the cytoplasm
