Interphase by biology flashcards on Flickr

Cell division is the process by which a parent cell divides into two or more daughter cells.

  • It is also known as CYTOKINESIS.
  • Interphase is when the cell grows and prepares for division.  It is during during this phase that DNA is duplicated.

Prophase by biology flashcards on Flickr

  • Genetic material in the nucleus is duplicated. 
  • The nuclear membrane disappears and centrioles appear at opposite sides of the cells with small fibers forming between them.

Remember:  CHROMOSOMES BECOME EASILY VISIBLE.

Metaphase by biology flashcards on Flickr

This is the phase where the spindle fibers attach themselves to the chromosomes that are thicker and have lined up at the equator of the cell. 


Pro-metaphase is the stage right before the fibers attach.


Remember:  CHROMOSOMES MOVE TO THE MIDDLE OF THE  CELL.

Anaphase by biology flashcards on Flickr

The duplicate pairs of chromosomes separate and move toward the two ends of the cell.

 

 

Remember: PAIR OF CHROMOSOMES MOVED TO OPPOSITE POLES.

Telophase by biology flashcards on Flickr

Two new nuclei start to re-form, the chromosomes become less visible and the cell separates into two new cells.  The two cells are identical.

 

 

Remember:  2 NEW CELLS ARE FORMED!
