Mitosis and Meiosis
By: 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.
