Look at the illustrations below and make sure your illustrations are labeled
and have the minimum information that they have.
Make sure that you have at least the information in the descriptions below.
Check your spelling.
Make sure you use color in your illustrations.
Mitosis is the process of a eukaryotic somatic cell separating into two identical daughter cells to increase in
numbers.


Mitosis can take place in diploid or haploid cells.
A cell contains chromosomes and when the cell goes through mitosis it must replicate the DNA so it
can be transferred into the other identical cell.
Mitosis takes place in one cell division and the two daughter cells (progeny) are identical to the
progenitor (mother).
A Eukaryotic cell may divide by mitosis or meiosis.
Why would a cell undergo mitosis?
During an organism’s life, the cells within that organism will need to divide. Some reasons are followed:
1. To replace dead or worn-out cells (Ex. Epithelial cells on the surface on your skin, the cells in your GI tract,
especially the ones in your stomach.)
2. When an organism is growing (adolescent/child), it will need to create more cells to compensate its growth.
Description

Nuclear membrane disappears

Chromosomes start to develop sister
chromatids (Chromosomes become
condensed)

Spindle apparatus forms and migrates
towards the end of the cell
Signals the beginning of prophaseChromosomes condense
Signals the end of prophase- nuclear
membrane disappears
Description

The chromosomes align on the
equatorial plane.

This is caused by the tension of the
pull from both centrosomes

The equatorial plane is equal distance
from both ends
Signals the beginning of metaphaseConnection of kinetochores to chromosomes
Signals the end of metaphase-Chromosomes
align in the middle of the equatorial plane
Description

The sister chromatids are cleaved
(split) and become separate daughter
chromosomes (they are separated).

The spindle fibers/microtubules pull
the daughter chromosomes towards
their respective ends.
Signals the beginning of anaphase-when sister
chromosomes are aligned on the equatorial
plane.
Signals the end of anaphase-when the
chromosomes have reached opposite poles.
Description

Corresponding daughter
chromosomes attach to opposite ends
of the cell

A new membrane forms around the
respective daughter chromosomes

The nucleus appears

The daughter chromosomes start to
uncoil

Mitosis is complete but not the cell
cycle
Signals the beginning of telophase-When the
daughter chromosomes are at opposite ends
of the cell.
Signals the end of telophase-When the
chromosomes uncoil.
Cytokinesis
Description

Not a part of telophase

A contractile ring pinches the
equatorial plane, thus creating cleavage

Once each nucleus is completely
separated, the cell cycle is complete!
