Cell Reproduction

Cell Reproduction – Mitosis 4. 4 mitosis 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: 1. 2. 3. 4. Prophase Metaphase Anaphase Telophase

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

Interphase • Cell grows and prepares to divide. Performs normal function. (G 1 phase) • DNA replication (S phase) • Organelles copied and more growth (G 2 phase)

Prophase First phase of Mitosis-____ • 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
