Mitosis Foldable
Use this sheet and your notes to complete the foldable.
Phase One:
 On the front of the flap:
o Use the yellow paper to draw a picture of what is happening in this phase
and label the parts (you should have: nuclear membrane, cell membrane,
nucleolus, chromatin, centrioles and cytoplasm
o On the inside of the flap write the name of the phase, interphase
o On the white paper write what is happening during this phase:
 During interphase the cell grows, makes a copy of its DNA and
prepares to divide into 2 new cells
 Animal cells make a copy of the centrioles, plant cells do not
Phase Two:

Phase Three:

Phase Four:

On front of flap:
o
Draw picture of what is happening and label with the
following: sister chromatids, centromere, nuclear membrane
disappearing, spindle fibers and centrioles
o On inside of flap write name of phase, prophase
o On white paper write what is happening:
 Spindle fibers begin to form
 Chromosomes become visible
 Nuclear membrane/envelope breaks down
 The centrioles move to opposite sides of cell
On front of flap
o Draw picture of what is happening and label with the following: spindle
fibers, centrioles, chromatids, centromeres
o On inside of flap write name of phase, metaphase
o On white paper write what is happening during metaphase:
 Each chromosome/chromatid attaches to the spindle fiber in the
middle of the cell by the centromere
On front of flap
o Draw picture of what is happening and label with the following: spindle
fibers, centrioles, chromatids, centromeres
o On inside of flap write name of phase, anaphase
o On white paper write about what is happening during anaphase:
 The centromeres split and pull the chromosomes apart
 The spindle fibers pull the chromosomes to opposite ends of the
cell
 The chromatids are called chromosomes after they separate
Phase Five:

On front of flap
o Draw picture of what is happening and label with the following: chromatin,
2 new nuclei, cell pinched in middle
o On inside of flap write name of phase, telophase
o On white paper write what is happening during telophase:
 The spindle fibers disappear
 Chromosomes start to uncoil
 Two new nuclei form
 Cell membrane starts to pinch inward to create 2 new cells
 Final stage of mitosis

On front of flap
o Draw picture of what is happening and label with the following: 2 daughter
cells, nuclear membrane, chromatin, nucleus for each cell
o On inside of flap write name of phase, cytokinesis
o On white paper write what is happening during cytokinesis:
 Cytokinesis starts at about the same time as telophase
 Cytoplasm divides during cytokinesis
 When complete 2 daughter cells have same number of
chromosomes as parent cell
 Since the rigid cell wall on plant can’t pinch in like the cell
membrane it creates a cell plate across middle of cell. Cell
membranes are then created and cell walls form last
 The 2 new cells inter interphase and begin the cycle again
Phase Six:
