INTERPHASE

Cell Growth
Chromatin is elongated and NOT visible
Distinct Nucleus
DNA replication takes place (makes a
copy)
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
chromosome away from each other
• Cytoplasm division begins

TELOPHASE
•
Nuclear membrane begins to reform
•
Chromosomes begin to uncoil and become less visible
•
Cytoplasm division occurring (Furrowing in animal cells; Formation of cell
plate in plant cells

CYTOKINESIS

http://www.auburnschools.org/drake/jwilliams/Cytokinesis%202.jpg
The division of the cytoplasm
Different in plant and animal cells
Plant cells, cell plate reaches the cell wall
Animal cells, Furrowing completes and cell
pinches off into two new cells
