Cell division is the process by which cells can make more cells. It only allows organisms to become more complex, it also allows organisms to replace cells and repair tissue. Engage students with premade activities at Storyboard That.
What are the Phases of Meiosis I and Meiosis II? Have students create a comic illustrating the phases of meiosis.

Meiosis I
PROPHASE I
PROPHASE
METAPHASE I
Metaphase
ANAPHASE I
Anaphase
TELOPHASE I
TELOPHASE
Chromosomes condense and spindle fibers start to form. The chromosomes pair up with the homologue partner. The homologous pairs then swap fragments in a process known as crossing over.
PROPHASE II
Spindle fibers attach the chromosome pairs and move them to line up on a line known as the metaphase plate.
METAPHASE II
The cell elongates as the homologous parts are pulled apart by the spindle fibers. The sister chromatids stay together.
ANAPHASE II
Two new nuclei form and the spindle fibers break down. The cells become separate through a process known as cytokinesis.
TELOPHASE II
Meiosis II
Chromosomes condense and spindle fibers start to form.
Spindle fibers attach to the chromosomes. The chromosomes are lined up along the center of the cell, at a point known as the metaphase plate.
The cell elongates as the sister chromatids are pulled apart by the spindle fibers.
Two new nuclei form from each haploid cell. The spindle fibers break down. The gametes separate from each other through a process known as cytokinesis.
