Mitosis is the process of cell division where a parent cell divides into two daughter cells that are identical to each other and to the original cell. It occurs in somatic cells and allows for organism growth, tissue repair after injury, and replacement of dead cells. The main stages of mitosis are interphase, prophase, metaphase, anaphase, and telophase where the chromosomes condense and duplicate, align in the center, separate, and move to opposite sides to form two distinct daughter nuclei.

1. MITOSIS
CELL DIVISION

2. • WHAT IS CELL DIVISION?
• WHY DO CELL UNDERGO THIS PROCESS?
• WHAT ARE ITS SIGNIFICANCE IN A HUMAN BODY?

3. DEFINITION
• MITOSIS IS THE DIVISION OF CELLS INTO TWO IDENTICAL CELLS. THE RESULTING
CELLS ARE IDENTICAL TO EACH OTHER AND ALSO TO THE ORIGINAL CELL.
• THIS PROCESS OCCURS IN EVERY SOMATIC CELL (BODY CELLS) AND NOT IN SEX
CELLS.

4. FUNCTIONS OF MITOSIS
• GROWTH IN ORGANISMS
• TO REPAIR INJURED CELLS OR TISSUES
• TO REPLACE DEAD CELLS
• FOR ASEXUAL REPRODUCTION

5. MITOSIS CONSIST OF FIVE PHASES
1. INTERPHASE
2. PROPHASE
3. METAPHASE
4. ANAPHASE
5. TELOPHASE

6. INTERPHASE
• THIS IS THE LONGEST STAGE IN
THE EUKARYOTE CELL CYCLE.
• CELLS BUILT UP ENOUGH ENERGY FOR
THE DIVISION PROCESS.
• DNA REPLICATION OCCURS
• INTERPHASE IS DIVIDED INTO 3 DISTINCT STAGES,
GAP 1, SYNTHESIS, AND GAP 2

7. PROPHASE
• THIS IS THE FIRST STAGE OF CELL DIVISION, BEGINNING AFTER INTERPHASE.
• THE CHROMATIN CONDENSES INTO CHROMOSOMES
• NUCLEOLUS DISAPPEARS

8. METAPHASE
• CHROMOSOMES ARRANGE RANDOMLY IN THE MIDDLE OR EQUATOR, EACH
SINGLE CHROMOSOME ATTACHING TO A SEPARATE SPINDLE FIBER BY MEANS OF
THE CENTOMERE

9. ANAPHASE
• CHROMOSOMES ARE PULLED IN OPPOSITE DIRECTIONS
• CENTROSOMES ATTACHING CHROMATIDS OF THE CHROMOSOMES SPLITS IN
HALF.

10. EARLY TELOPHASE
• DAUGHTER CHROMOSOMES REACH POLES.
• NUCLEAR ENVELOPE SURROUNDS CHROMOSOMES.
• NUCLEOLUS REAPPEARS AT EACH POLE.
• CHROMOSOMES BECOME LESS CONDENSE
FORMING CHROMATIN.
• TWO IDENTICAL NUCLEI HAS BEEN FORMED

11. LATE TELOPHASE
• INVAGINATION OF THE CYTOPLASM AND PLASMA MEMBRANE OCCURS.
• CONTINUES UNTIL THE CELL IN DIVIDED INTO TWO SEPARATE AND IDENTICAL
CELLS.
( IDENTICAL TO ONE ANOTHER AND THE ORIGINAL CELL)
