Mitosis Quiz Review

Friday, February 13th

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 eukaryoticcells 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 followsanaphasetelophase

The first phase of MitosisProphase

This network of fibersthat attach and pullthe chromosomesapart 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, 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 (phase in interphase)

G1 of interphase

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 organelles needed for cell division G2

Two identical chromosomes that make up a duplicated chromosome ______________ Sister chromatids

These structuresat the poles whichattach 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 followsmetaphaseanaphase

Phase of the cell cycle that follows G1 S

This cell is in___________anaphase

Phase of cell division in whichthe nuclear membrane returns and chromosomes 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 mitosis in which chromatids separate and move to opposite ends of the cell.

anaphase

The very first dividing phase in Mitosis: _______________prophase

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 two:Cytokinesis
