Involves splitting of cytoplasm into 2 (mitosis) or four (meiosis) - Cell surface membranes (and cellulose cell walls in plant cells) form to separate cells. (4, 8) 6. Represents the total no. of chromosomes in a normal body cell. (7, 6) 8. Cell divides into 2 (mitosis) or four (meiosis) separate cells. (4, 8) 10. Uncontrolled cell division and growth results in group of abnormal cells called a.. (6) Down 1. A group of diseases caused by uncontrolled growth and rapid division of cells. (6) 2. Nucleus divides into 2 (mitosis) or 4 (meiosis). (7, 8) 3. Represents a single set of chromosomes. (7, 6) 5. Another word for cell division. (11) 7. Centromere splits and identical sister chromatids separate - Identical sister chromatids are pulled to opposite poles of cell by spindle microtubules. (8) 9. Each chromosome consists of 2 identical sister chromatids joined together by a centromere - Each chromosome then shortens and thickens - Centrioles move to opposite poles of cell - Nuclear membrane breaks down.
