Mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells.

2. What is mitosis?What is mitosis?
Mitosis is the process where a single parent cell divides
to make two identical daughter cells.
Happens in somatic cells / body cells

3. Unicellular organisms undergo
mitosis to reproduce asexually.
Multicellular organisms undergo
mitosis to create new cells for
growth and repair old cells.

5. The cell grows in size and replicates its
DNA to prepare for cell division.
INTERPHASEINTERPHASE
This stage occurs before mitosis begins.

6. The chromosomes (genetic material)
condense (coil tightly) and the nucleolus
disappears.
PROPHASEPROPHASE
Centrosome separate, moving to opposite
ends of the nucleus.

7. The chromosomes align in the center
of the cell called metaphase plate and
attach to microtubules in preparation
to split apart.
METAPHASEMETAPHASE

8. Chromatids separate and move to
opposite ends of the cell.
ANAPHASEANAPHASE
This stage ensures that each cell contains
identical chromosomes after splitting.

9. Two new nuclei form around each
set of chromosomes.
TELOPHASETELOPHASE
Chromosomes decondense and the cells
begin to split from each other.

10. Formation of cleavage furrow - a
shallow groove in the cell near the
old metaphase plate
TELOPHASETELOPHASE

11. The cytoplasm of the parent cell splits
to form two identical daughter cells.

13. RESULTS OF MITOSISRESULTS OF MITOSIS
Two daughter nuclei
Each with the same chromosome
number as parent cell (2n)
Genetically identical to each other
and the parent cell

14. Permits growth and repair
In plants, it retains the ability to divide
throughout the life of the plant.
In mammals, mitosis is necessary to:
Fertilized egg becomes and embryo1.
Embryo becomes a fetus2.
Allows a cut to heal or a broken bone to mend3.
