KEY Phases of Cell Division KEY
Prophase
Metaphase
Spindle fibers
A. Prophase
B Metaphase
Spindle fibers attach to chromosomes,
chromosomes align on metaphase plate.
Centrioles
Chromosomes condense,
nucleolus disappears,
centrioles move to opposite
sides of the cell, spindle fibers
start to form.
chromosome
Nuclear membrane
Anaphase
Interphase
Cell membrane
nucleolus
Centrioles
Telophase
C Anaphase
Chromatin
Spindle fibers shorten, sister chromatids are
pulled apart by contracting fibers, move to
opposite poles, poles start to pull apart.
E Interphase
G1 (cell enlarges, organelles made), S (DNA
replicates), G2 (cell grows); DNA in form of
chromatin.
Daughter cells
D Telophase

Chromatids
Nuclear envelope reforms, chromosomes
disperse, spindle fibers dissolve, CYTOKINESIS
happens (when the cytoplasm divides)
