MITOSIS
• There are about 50 trillion cells in
the human body
• If you get an injury, you lose cells
How can you grow more cells?
Mitosis = a cell divides in half to make
2 identical cells (2 clones)
daughter cell
Parent cell
MITOSIS
In mitosis, a cell divides 1 time; 1 cell
division occurs
The cells produced by mitosis are
identical to the parent cell
daughter cell
Parent cell
Why do our cells undergo or
“do” mitosis?
• Cells do mitosis to help our bodies
grow and repair themselves
• Unicellular organisms (1 cell--like
bacteria) do mitosis to reproduce
• Asexual reproduction: reproduction with
1 parent
Mitosis (notes)
• Mitosis happens in 4 stages
• Chromosome: strand of DNA
Mitosis (notes)
Stage 0: Interphase
Before mitosis starts
Description: Genetic
material is loose (not
formed in chromosomes)
the cell is preparing for
cell division
the cell obtains nutrients,
grows, and conducts its
“normal” functions
Mitosis (notes)
Stage 1: Prophase
Description:
chromosomes form
chromosomes
condense
Mitosis (notes)
Stage 2: Metaphase
Description:
• Chromosomes line up
in the center of the
cell
• Each chromosome
connects to a spindle
Mitosis (notes)
Stage 3: Anaphase
Description:
Chromosomes split and
spindles pull them to
opposite ends of the cell
Mitosis (notes)
Stage 4: Telophase
Description:
Chromosomes gather at
opposite ends of the cell
Mitosis
“Stage 5”: Cytokinesis
Description:
Separation of cytoplasm
resulting in two distinct
daughter cells
