Cell Cycle & Mitosis
Quiz Review
Thursday,
th
February 11
This spot that holds the 2
chromatid copies
together is called a
centromere
______________________
The first and longest phase
of the cell cycle Interphase
Type of cell division in eukaryotic
cells that results in 2 identical
daughter cells.
mitosis
List the phases of the cell cycle
starting with Interphase:
Interphase, Prophase, Metaphase,
Anaphase, Telophase, and Cytokinesis
Phase of mitosis that follows
anaphase
telophase
The first phase of Mitosis
Prophase
This network of fibers
that attach and pull
the chromosomes
apart is called:
______________
Spindle fiber
This cell is in
__________________
prophase
G1, S, and G2 make up this
phase of the cell cycle. interphase
Sister chromatids are held
together by this structure
Centromere
______________
The place in the cell membrane
of an animal cell that pinches
in during cytokinesis is called
a __________________
cleavage furrow
Plant cells can’t pinch to divide,
cell plate
instead they form a _______________
to divide.
This phase of the
cell cycle is
anaphase
______________
Part of interphase in which the
cell grows to mature size and carries
out its job. G1
Phase of mitosis that follows
prophase metaphase
Phase of the cell cycle that follows S
G2
This phase of the
cell cycle is
metaphase
________________
Phase of the cell cycle cell’s spend
most of their time in (phase in interphase)
G1 of interphase
DNA that is all spread out in
an interphase nucleus is
called
chromatin
________________
Phase of mitosis in which the
nuclear membrane and nucleolus
disappear and the DNA scrunches
into chromosomes.
prophase
In this part of interphase cells
make the molecules and
organelles needed for cell
division G2
Two identical chromosomes
that make up a duplicated
chromosome ______________
Sister chromatids
These structures
at the poles which
attach to the
spindle fibers and
pull the
chromosomes. centrioles
What phase is the cell in?
metaphase
When chromatin scrunches
together it is called a
chromosome
_________________
The picture below is showing:
Sister chromatids
Phase of mitosis that follows
metaphase
anaphase
Phase of the cell cycle that
follows G1 S
This cell is in
___________
anaphase
Phase of cell division in which
the nuclear membrane returns
and chromosomes spread out
into chromatin. telophase
This cell is in
__________
telophase
The cell above is a Plant
_________ cell.
animal
You can see the cell plate
forming in center instead
plantof a cleavage furrow.
Phase of mitosis in which
chromatids separate and move
to opposite ends of the cell.
anaphase
The very first dividing phase
prophase
in Mitosis: _______________
This is called a
Cleavage furrow
______________
an animal
This cell is _____________
cell.
Plants don’t have cleavage furrows.
an animal
a plant
Phase of mitosis where the
cytoplasm splits into two:
Cytokinesis
Name the phases of Mitosis in order:
Prophase, Metaphase,
Anaphase, Telophase

Prophase (P) Metaphase (M) Anaphase (A)
Telophase (T)
Interphase (I)
INTERPHASE
________________ DNA is all spread out as
chromatin and nuclear membrane is visible
PROPHASE
________________ DNA scrunches up and
chromosomes are first visible
INTERPHASE
________________
Made up of G1, S, G2
METAPHASE
________________
Chromosomes line up in
middle of cell
Prophase (P)
Telophase (T)
Metaphase (M) Anaphase (A)
Interphase (I)
INTERPHASE
_______________ DNA is copied and cell prepares
to divide
ANAPHASE
_______________
Chromatid arms separate and
move to opposite ends of the cell
_______________
TELOPHASE Chromosomes unwind into
chromatin & nucleus returns
PROPHASE
_______________
Nuclear membrane & nucleolus
disappear
Prophase (P)
Telophase (T)
Metaphase (M) Anaphase (A)
Interphase (I)
TELOPHASE
_________________
Two nuclei are visible
