Phase of the cell cycle in which DNA is copied 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

List the phases of mitosis in order starting with prophase. 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

Phase of mitosis that follows anaphase telophase Phase of the cell cycle that follows G2 Mitosis (prophase)

This cell is in _____________ This network of fibers that attach and pull the chromosomes apart is called the ______________ Spindle Fiber 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 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 prophase metaphase Phase of the cell cycle that follows S G2

Phase of the cell cycle cell’s spend This phase of the cell cycle is ________________ metaphase Phase of the cell cycle cell’s spend most of their time in. G1 of interphase

One of 2 identical arms that make up a chromosome Disorder in which body cells lose their ability to control cell division cancer One of 2 identical arms that make up a chromosome chromatid

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

same shape, and carry genes for the same traits. In this part of interphase cells make the molecules and organelles needed for cell division G2 The 2 copies of each chromosome are called ______________ chromosomes because are the same size, same shape, and carry genes for the same traits. homologous

These structures at the poles which attach to the spindle fibers and pull the chromosomes. centrioles The cell above is in ______phase meta

One of 2 identical arms that make up a chromosome When chromatin scrunches together it is called a _________________ chromosome One of 2 identical arms that make up a chromosome chromatid

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 _________ cell. Plant You can see the cell plate forming in center instead of a cleavage furrow.

Substance that causes cancer carcinogen Phase of the cell cycle after S phase in which cells make the molecules and organelles needed for cell division G2

The very first dividing phase is _______________ Phase of mitosis in which chromatids separate and move to opposite ends of the cell. anaphase The very first dividing phase is _______________ prophase

List the phases of cell division in order starting with interphase 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 cell division in order starting with interphase Interphase, prophase, metaphase, anaphase, telophase, cytokinesis

This is called a ______________ Cleavage furrow This cell is _____________ cell. an animal Plants don’t have cleavage furrows.

Phase of mitosis where the cytoplasm splits into two CYTOKINESIS Name the phases of the cell cycle in order starting with G1 G1 S G2 M C

Prophase (P) Metaphase (M) Anaphase (A) Telophase (T) Interphase (I) INTERPHASE ________________ 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 PROPHASE INTERPHASE METAPHASE

_______________ DNA is copied and cell prepares to divide 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
