Mitosis How do living things grow and repair themselves? Living things must grow and develop. At times they suffer injuries or damage, or cells simply wear out. New cells must be formed for the organism to survive. What process must occur to make a new, properly- functioning cell? Model 1 – Mitosis as Part of the Cell Cycle Prophase Metaphase Anaphase Telophase Replicated chromosome (2 sister chromatids) Nuclear membrane Spindle fibers Centriole Mito sis (Nuc l ear Divis ion) Cyto kine s is (Cyto plas m ic Divis ion) 1. Refer to Model 1. List the four phases in the mitosis process. Prophase, metaphase,anaphase,telophase 2. Where is mitosis in the cell cycle? Before G1 and after G2 . 3. What three phases of the cell cycle are considered interphase? G1,S phase, G2 4. Refer to the cell cycle shown. a. How many cells are present at the beginning of mitosis? 1 b. How many cells are present at the end of mitosis? 2 My so it u or c s e i w s as 1 G0 G1 * M (including cytokinesis) G2
