What is it?
Why do Cells do it?
Why is it important to me?
Also known as Mitosis
Takes place in Regular Body Cells
Keeps Cells Living and Growing
The longest stage of a Cell’s life
The time spent between divisions
Produces all materials required for growth
Preparation for division
(Synthesis Phase – when DNA duplicates)
Next step –
The last part of the Cell Cycle is called Mitosis and has 4 phases during which the cell divides into 2 cells
4. The spindle
and attaches to
The third phase of Mitosis
Diploid sets of daughter chromosomes separate
They are pushed and pulled toward opposite poles of the cell by the spindle fibers
The nuclear membrane and nucleoli (nucleus) reform.
Cytokinesis is nearly complete,
The Cell prepares for finial division
The cytoplasm, organelles, and nuclear material are evenly split and two new cells are formed.
The following slides are drawings of the stages of Mitosis. On your notes, please draw each phase and label it.
Chromosomes consisting of 2 Sister Chromatids
Pair of Centrioles
Equator, or Metaphase Plate
Quick Review: Identify What happens in each phase of Mitosis:
The larger a cell becomes, the more demands the cell places on it's DNA.
It also has more trouble moving enough food and wastes across its cell membrane.
The bigger the cell gets the harder it becomes to move food and waste across the membrane
Waste goes out
This happens because the surface area and volume ratio does not stay the same as the cell size increases.
