Cell Reproduction

Cell Reproduction – Mitosis 4.4 1. The M in M phase stands for __________. 2. Mitosis is the: Division of the cell’s nucleus into 2 nuclei 3. Mitosis has 4 stages: Prophase Metaphase Anaphase Telophase mitosis

Cytoplasmic Division 4. The cell’s cytoplasm divides to form the 2 new cells in the process called __________. 5. The 2 resulting cells are _________ to each other and to the ________ cell. 6. Each new cell has the ______ number of chromosomes as the original cell. cytokinesis identical parent same

Interphase Cell grows and prepares to divide. Performs normal function. (G1 phase) DNA replication (S phase) Organelles copied and more growth (G2 phase)

First phase of Mitosis-________ Prophase Chromosomes become visible Nuclear envelope dissolves Centrioles move to opposite poles Spindle begins to form

Metaphase Spindle attaches to the centromere of the chromosomes Chromosomes line up along the equator of the cell

Anaphase Centromeres divide Chromosomes move toward opposite poles

Telophase Nuclear envelope forms around each set of chromosomes Spindle dissolves Chromosomes uncoil

__________ Cytokinesis Cytoplasm divides Two new daughter cells form
