Mitosis is the process of cell division that results in two daughter cells each having the same number and type of chromosomes as the parent nucleus. It has four main stages: prophase, metaphase, anaphase, and telophase. During prophase the chromosomes condense and the nuclear envelope breaks down. In metaphase the chromosomes line up along the center of the cell. In anaphase the chromosomes are pulled towards opposite poles of the cell. Finally in telophase the daughter nuclei form and cytokinesis completes the division of the cytoplasmic contents, resulting in two identical daughter cells each with the full complement of chromosomes. Mitosis is important for growth, tissue repair, asexual reproduction, and replacement of old or

1. MITOSIS

2. OBJECTIVES
To understand the mechanism of mitotic
cell division
To understand the significance of mitosis

3. STAGES OF
MITOTIC CELL
DIVISION
PROPHASE
METAPHASE
ANAPHASE
TELOPHSAE

4. INTERPHASE PROPHASE
Cell membrane
Centriole
Nuclear
membrane
Nucleolus
Chromosomes
Chromosomes get spirally coiled
and become shorter
Centriole divides and
move towards the poles
Nuclear membrane and
nucleolus disappeared
The centrioles develop
spindile fiberes

5. METAPHASE
The chrmosomes divide
in to four chromatids
Spindle fiberes pull the
chromosomes towards
the equater

6. ANAPHASE
The chromosomes move
towards the poles
The spindle fibres slowly
disappears
The nuclear membrane
becomes appears

7. TELOPHASE
The nuclei are fully
formed---the division of
nucleus is called kariokinesis
The nuclear membrane slowly
appears and the
chromosomes become cioled
The mother cell divides
in to two daughter cells

8. SIGNIFICANCE OF MITOSIS
It happens during embryonic development,
growth and renewal of old tissues
