Name the three important functions of mitosis and cytokinesis
1) Growth 2) Maintenance 3) Repair
What are the four phases of mitosis?
1) Prophase 2) Metaphase 3) Anaphase 4) Telophase
A list of key events in ________ of Mitosis:

-nucleus contents visible
-chromatin---> Chromosomes
-Centrioles separate and move to opposite poles
-nuclear envelope disappears
-nucleus becomes invisible.

What phase of mitosis is this?
Prophase
-Chromosomes move to the center of the cell
-centromeres on the equator
-spindle fibres attach to the centromere

What phase of mitosis is this?
Metaphase
-Chromatids separate at the centromeres
-Chromatids move to opposite poles of the cells
-Same number of single copy chromasomes should be at each pole

What phase of mitosis is this?
Anaphase
-Chromosomes at opposite ends of the cell
-decondense to form chromatin
-nuclear envelope reappears

What phase of mitosis is this?
Telophase
mitosis is a process of nuclear division and it is followed by ________
Cytokinesis
What process has the following steps?

-cytoplasm division
-cell membrane pinches in to form two distinct cells
-ends with separation of two identical daughter cells. The daughter cells are now in G1 of interphase
Cytokinesis
How do Cytokinesis and Mitosis differ in a plant and animal cell?
Plants do not have centrioles but they form a spindle apparatus
-Rigid cell wall of a plant is much stronger than membrane of animal cell
-Cell wall does not pinch during cytokinesis (in plant)
-Instead, membrane called cell plate forms between the two daughter cells creating a new cell wall.
