CA… Mr Alvarez
Overview
Mitosis is the process of nuclear cell division. During
division, the nucleus of the cell divides, resulting in
two sets of identical chromosomes, or organized DNA
proteins. This process is almost always accompanied
by a process called cytokinesis, in which the rest of
the cell divides, leading to two completely separate
cells, called daughter cells.
Daughter
Original
In mitosis, a cell replicates
its DNA before dividing into
two daughter cells

Purpose
One of the main purposes of this process is the natural
growth of the parent organism. It's also done to
replace cells that are worn out, damaged, or just at the
end of their natural lifespan. The average length of the
mitosis process is 20-24 hours.

4 Phases
Length of Process is 6 total phases, but there
are four phases in the Mitosis process that we
discuss. The other two phases are a period of
quick growth of the cell then getting ready to
begin mitosis again…

• There are a number of reasons for this
process, including
• Reproduction
• Replacement of cells
• Growth

Mitosis Cycle
Asexual Reproduction
Asexual reproduction is a mode of reproduction
where offspring come from one organism and
inherit the exact DNA from one parent. Usually
there are two twin cells called daughter cells.
Organisms that use asexual reproduction
•
•
•
Plants and fungi
Single celled organisms
Archaea, bacteria, and protists
Budding and Regeneration
Regeneration is when an
organism loses a limb and
regrows it and budding is
when an organism grows
an entire new copy of
itself.
Examples of
regeneration:
• Starfish
• Lizard
• Examples of budding:
• Fungus
• Bacteria
