CELL DIVISION MITOSIS

Stages of Cell Division 1. Interphase 2. Prophase 3. Metaphase 4. Anaphase 5. Telophase

Interphase Cells begin to prepare for division. Chromosomes appear more visible with a thread-like appearance.

Prophase Chromosomes shorten and thicken forming Chromatids. Nuclear membrane disappears the spindle fibres begin to appear.

Metaphase The chromatids arrange themselves on the equator (middle) region of the cell.

Anaphase Spindle fibres stretch and the chromatids separate and move to opposite ends.

Telophase Cell membrane divides into two (2) producing daughter cells for each cell.

Complete Division In Mitosis, the cells regain their nuclear material and division is complete. While it’s not complete in Meiosis because chromatids still lack a thread-like appearance.

Importance Leads to growth because it adds new cells to already existing cells. Repairs body parts of living organisms. Helps in asexual reproduction like binary fission, micro-organisms and vegetative reproduction in plants.
