Mitosis Stages Drawing Sheet
Regular Pen or Pencil
Brown Colored Pencil

Purple Colored Pencil
INTERPHASE
• G1:
Cells
Grow and
Develop
Nuclear
envelope and
nucleous are
present
Chromatin is
present
INTERPHASE
• S (SYNTHESIS):
Chromatin doubles:
DNA replicates; makes a
copy of each chromosome
Nuclear
envelope and
nucleous are
present
If the chromosomes were
condensed, they would
look like this:
Sister
(Homologous Chromatids
pair)
INTERPHASE
• G2:
Nuclear
envelope and
nucleous are
present
Cell makes
organelles and
gets larger
PROPHASE
Centrioles (2)
form & start to
move to the
poles
Nuclear
envelope and
nucleous
disappear
Spindle starts to
form & may
begin to attach
to centromeres
(draw on next
phase)
Centromere =
holds the
sister
chromatids
together
METAPHASE
Chromosomes
line up in the
middle on
Metaphase
Plate
Metaphase Plate:
imaginary line
down center of
cell
Spindle fibers
(attached to
centromere of
each sister
chromatid)
ANAPHASE
Spindle fibers
pull sister
chromatids to
opposite sides of
the cell
Centromeres
divide
Will become
Independent
Daughter
Chromosomes
TELOPHASE
2 nuclei
reappear
around each set
of
chromosomes
Chromosomes
start to uncoil
back into
chromatin
Spindle
fibers
dissolve
Centrioles
stay, but
move from
poles
Each daughter
cell has exact
amount of
chromosomes
as the parent
CYTOKINESIS: Cytoplasm Division
Cell membrane
pinches in
forming a
CLEVAGE
FURROW
1. Membrane
fragments gather
in center forming
CELL PLATE
(becomes the cell
membrane)
2. Cell wall
forms between
the membranes
ANIMAL CELLS
PLANT CELLS
