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

S

G0

S G1 G2 G0 Mitosis (M) Cytokinesis (C)

_______ Division of cytoplasm happens

_______ Cell makes the molecules and organelles

needed for cell division

_______ Made up of telophase, anaphase, prophase,

and metaphase
