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 anaphase telophase Phase of the cell cycle that follows G2 Mitosis (prophase) This network of fibers that attach and pull the chromosomes apart is called the mitotic ______________ spindle This cell is in __________________ prophase G1, S, and G2 make up this phase of the cell cycle. interphase Plant cells can’t pinch to divide, instead they form a _______________ cell plate to divide. This phase of the cell cycle is anaphase ______________ Part of interphase in which the cell grows to mature size and carries out its job. G 1 Phase of mitosis that follows prophase 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 spend most of their time in. G1 of interphase 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 In this part of interphase cells make the molecules and organelles needed for cell division G2 The 2 copies of each chromosome are called ______________ homologous chromosomes because are the same size, same shape, and carry genes for the same traits. These structures at the poles which attach to the spindle fibers and pull the chromosomes. centrioles The cell above is in ______phase meta When chromatin scrunches together chromosome it is called a _________________ 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 animal plant You 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 opposite ends 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 an animal This cell is _____________ cell. Plants don’t have cleavage furrows. an animal a plant 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 Prophase (P) Metaphase (M) Anaphase (A) Telophase (T) Interphase (I) INTERPHASE ________________ DNA is all spread out as chromatin and nuclear membrane is visible PROPHASE ________________ DNA scrunches up and chromosomes are first visible INTERPHASE ________________ Made up of G1, S, G2 METAPHASE ________________ Chromosomes line up in middle of cell Prophase (P) Metaphase (M) Anaphase (A) Telophase (T) Interphase (I) INTERPHASE _______________ DNA is copied and cell prepares to divide ANAPHASE _______________ Chromatid arms separate and move to opposite ends of the cell _______________ TELOPHASE Chromosomes unwind into chromatin & nucleus returns PROPHASE _______________ Nuclear membrane & nucleolus disappear Prophase (P) Metaphase (M) Anaphase (A) Telophase (T) Interphase (I) TELOPHASE __________________ Two nuclei are visible __________________ PROPHASE First dividing phase PROPHASE ___________________ Centrosomes containing centrioles & spindle fibers appear next to nucleus __________________Cytoplasm is split between two cells CYTOKINESIS _________________ Spindle fibers and centrioles TELOPHASE disappear S G1 G2 Mitosis (M) Cytokinesis (C) G1 _______ Cell is reading the DNA code and “doing its job” S _______ Cell makes a copy of its DNA M _______ Division of chromosomes happens S G1 G2 Mitosis (M) Cytokinesis (C) C _______ Division of cytoplasm happens _______ Cell makes the molecules and organelles G2 needed for cell division M _______ Made up of telophase, anaphase, prophase, and metaphase THE END
