Mitosis Cell Division Single Cell Organisms -Reproduction -Assexual reproduction in which a single celled organisms divide in two creating two creating identical offspring Multicellular Organisms -Growth -Cell Division produces new cells -Repair -Damaged Cells are replaced by new cells -Ex. Cut your hand or break a bone Cell Division Parts DNA- contains the information that determines the traits that a living thing inherits and needs to live Chromatin- contain DNA and Protein Chromosomes- compacted chromatin; consist of two cromatid Cell Cycle The life of a eukaryotic cells is called the cell cycle can divided into three phases. They include Interphase, Mitosis, and Cytokinesis. Interphase The part of the cell cycle that is not dividing. The cell grows about twice the size it was when it was first produced. The cell engages in normal life. Cell Division Phases Prophase- Chromatin in the nucleus condense and become chromosomes; The membrane around the nucleus breaks down Inerphase Prophase Cell Division Phases Metaphase- Chromosomes line up in the middle of the cell Prophase Metaphase Cell Division Phases Anaphase- The chromatids separate and pulled to opposite side of the cell; Each cell ends up with a complete set of chromosomes Metaphase Anaphase Cell Division Phases Telophase-A new nuclear membrane forms around each group of chromosomes; Cell now two identical nuclei Anaphase Telaphase Cytokinesis Is the division of the parent cell’s cytoplasm. During cytokinesis the cell membrane pinches inward between the new nuclei Start of New Cell Cycle Both new cells start the cycle again.
