TRANSCRIPT
Warm Up!!!
What phases of Mitosis did
you see in the slides on
Thursday??
Chapter 10
Cell division
Review
This spot that holds the 2 chromatid copies together is called a
______________________centromere
Cell division in bacteria cells is called
_______________________ Binary fission
Phase of the cell cycle in which
DNA is copied
S (synthesis)
Phase of the cell cycle
in which the nuclear
membrane is present
and DNA is spread out
into chromatin.
interphase
Type of cell division in eukaryotic
cells that results in 2 identical
daughter cells.mitosis
List the phases of mitosis in order
starting with prophase.
Prophase, metaphase, anaphase,
telophase, cytokinesis
Phase of mitosis that follows
anaphasetelophase
Phase of the cell cycle that follows G2
Mitosis (prophase)
This network of fibersthat attach and pullthe chromosomesapart is called the
mitotic ______________spindle
This cell is in
__________________prophase
G1, S, and G2 make up this phase
of the cell cycle.
interphase
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,
instead they form a _______________
to divide.
cell plate
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
prophasemetaphase
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.
G1 of interphase
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 divisionG2
These structures
at the poles which
attach to the spindle
fibers and pull the
chromosomes.
centrioles
The cell above is in __________.metaphase
Phase of mitosis that follows
metaphaseanaphase
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 _________ cell.
(animal or plant)
PlantYou can see the cell plate
forming in center instead
of a cleavage furrow.
Phase of the cell cycle after S phase
in which cells make the molecules
and organelles needed for cell division
G2
Phase of mitosis in which chromatids separate and move to oppositeends of the cell.
anaphase
The very first dividing phase is
_______________prophase
Phase of the cell cycle where cells
spend most of their time. They
grow bigger and they do their job
as body cells.G1
List the phases of mitosis in order
starting with interphase
Interphase, prophase, metaphase,
anaphase, telophase, cytokinesis
This is called a
______________Cleavage furrow
This cell is _____________ cell.(animal or plant)
an animal
Plants don’t have cleavage furrows.
Phase of mitosis where the
cytoplasm splits into 2.
Cytokinesis
Name the phases of the cell cycle in
order starting with G1
G1 S G2 M C
________________ DNA is all spread out as chromatin
and nuclear membrane is visible
________________ DNA scrunches up and
chromosomes are first visible
________________ Made up of G1, S, G2
________________ Chromosomes line up in middle of
cell
INTERPHASE
PROPHASE
INTERPHASE
METAPHASE
Prophase (P) Metaphase (M) Anaphase (A) Telophase (T)
Interphase (I)
_______________ DNA is copied and cell prepares to divide
_______________ Chromatid arms separate and move to opposite ends of the cell
_______________ Chromosomes unwind into chromatin & nucleus returns
_______________ Nuclear membrane & nucleolus disappear
INTERPHASE
ANAPHASE
TELOPHASE
PROPHASE
Prophase (P) Metaphase (M) Anaphase (A) Telophase (T)
Interphase (I)
__________________ Two nuclei are visible
__________________ First dividing phase
___________________ Centrosomes containing centrioles & spindle fibers appear next to nucleus
__________________Cytoplasm is split between two cells
_________________ Spindle fibers and centrioles disappear
TELOPHASE
PROPHASE
PROPHASE
CYTOKINESIS
TELOPHASE
Prophase (P) Metaphase (M) Anaphase (A) Telophase (T)
Interphase (I)
_______ Cell is reading the DNA code and
“doing its job”
_______ Cell makes a copy of its DNA
_______ Cells leave the cell cycle and stop dividing
_______ Division of chromosomes happens
G1
