Mitosis and MeiosisBy: Karina Garcia

Vocabulary • Cell cycle: repeating set of

events that make up the life of a cell.

• Chromosomes: DNA and protein in a coiled, rod shaped form that occurs during cell division.

• Cytokinesis: is the division of the cytoplasm of the cell

• Binary fission: division of a prokaryotic cell into two offspring cells.

Meiosis and mitosis • Meiosis is a process of

nuclear division that reduces the number of chromosomes in a new cells to half the number in the original cell.

• Mitosis is the division of the nucleus, this occurs during cell division. Mitosis is a continuous process that is divided into four phases: prophase, metaphase, anaphase, and telophase.
