Cell divisionReview

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 whichDNA is copied

S (synthesis)

Phase of the cell cyclein which the nuclear membrane is presentand DNA is spread out into chromatin. interphase

Type of cell division in eukaryoticcells that results in 2 identical daughter cells.

mitosis

List the phases of mitosis in orderstarting with prophase.

Prophase, metaphase, anaphase, telophase, cytokinesis

Phase of mitosis that followsanaphase

telophase

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 phaseof the cell cycle.

interphase

Plant cells can’t pinch to divide, instead they form a _______________to divide.

cell plate

This phase of thecell cycle is______________anaphase

Part of interphase in which thecell grows to mature size and carries out its job. G1

Phase of mitosis that followsprophase

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 spendmost of their time in.

G1 of interphase

Disorder in which body cells lose their ability to control cell division

cancer

One of 2 identical armsthat make up a chromosome

chromatid

DNA that is all spread out inan interphase nucleus is called________________chromatin

Phase of mitosis in which thenuclear membrane and nucleolusdisappear and the DNA scrunches into chromosomes.

prophase

In this part of interphase cellsmake the molecules and organellesneeded for cell division

G2

The 2 copies of each chromosomeare called ______________ chromosomes because are the same size,same shape, and carry genes for thesame traits.

homologous

These structuresat the poles whichattach to the spindle fibers and pull the chromosomes.

centrioles

The cell above is in ______phase meta

When chromatin scrunches together it is called a _________________chromosome

One of 2 identical armsthat make up a chromosome

chromatid

Phase of mitosis that followsmetaphase

anaphase

Phase of the cell cycle that follows G1

S

This cell is in___________anaphase

Phase of cell division in whichthe nuclear membrane returns andchromosomes spread out into chromatin. telophase

This cell is in__________telophase

The cell above is a _________ cell.

animal plant

PlantYou can see the cell plate forming in center insteadof a cleavage furrow.

Phase of the cell cycle after S phasein which cells make the moleculesand 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 jobas body cells.

G1

List the phases of mitosis in orderstarting with interphase

Interphase, prophase, metaphase, anaphase, telophase, cytokinesis

This is called a ______________Cleavage furrow

This cell is _____________ cell.

an animal a plant

an animalPlants 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
