INTERPHASE
• Cell growth occurs
• Chromatin is elongated and not visible
• Distinct nucleus
• DNA replication takes place
• Cell appears to be resting

PROPHASE • Chromosomes become visible
• Nuclear membrane breaks down
• Centrioles and spindle fibers appear

Metaphase
Chromosomes line up in the middle of the cell
Spindle fibers attach to the centromere of the chromosomes

ANAPHASE
• Duplicated chromosomes separate
• Spindle fibers shorten pulling single chromosomes away from each other
• Cytoplasm division begins

Nuclear membrane starts to reformChromosomes begin to uncoil and become less visibleCytoplasm division occurring
CYTOKINESIS • The division of the cytoplasm
• Different in the plant and animal cells
• Plant cells, cells reach cell wall
• Animal cells, cells do no reach cell wall
