Cell division and health issues

1. CELL DIVISION MITOSIS Grade 10 learners NTSOANE T. 218015789

2. Cell division The process by which a cell reproduce itself. cell division occurs in two forms: mitosis and meiosis The cell cycle, which is the time between two cell divisions, contains two phases: interphase and mitosis

3. ebrary.net

4. Interphase Interphase takes up about 90% of the cycle The cell increase in size and prepares for division G1: cell growth and preparation for DNA replication S- DNA replication G2: more growth for mitosis

5. What is M itosis ? It is a process by which chromosomes replicate in a single cell and separate them to form two identical nuclei to prepare for cell division. Roles of mitosis 1. Growth 2. Replacement and repair 3. Asexual reproduction

6. Phases of Mitosis Prophase Metaphase Anaphase telophase

7. . www.vecteezy.com Pairs of chromatids called chromosomes are visible Nuclear membrane disappear Centrosome moves to the opposite poles forming a spindle

8. . fr.vecteezy.com Chromosomes line up at the equator of the cell Each chromosome is attached to spindle fibers at the centromere.

9. . www.vecteezy.com Spindle fibers pull sister chromatids apart Centromeres are pulled to opposite poles Sister chromatids move to the opposite poles of the cell

10. . ar.inspiredpencil.com Cytokinesis completes. A nuclear membrane and nucleolus form in each daughter cell Each daughter cell has the same number of chromosomes as the parent cell

11. Cytokinesis It is the division of the cytoplasm of the cell parent cell into two daughters cells It is the final stage of cell division In animals cells, it involves the formation of cleavage furrow. The constriction divides the cell into two In plant cells, it involves cell plate in the middle that grows into a cell wall to separates the two cells

12. Cancer Cancer is a disorder caused by uncontrolled cell differentiation and growth Tumor is a swelling caused by changes that affect the cell cycle Two types of tumor 1 benign: cell masses that don’t spread 2 malignant: cancerous cells that break loose and travel to distant sites to invade other organs during metastasis.
