Cell Cycle & Mitosis Quiz Review Thursday, th February 11 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 eukaryotic cells 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 follows anaphase telophase The first phase of Mitosis Prophase This network of fibers that attach and pull the chromosomes apart 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, cell plate instead they form a _______________ 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. G1 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 (phase in interphase) G1 of interphase 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 Two identical chromosomes that make up a duplicated chromosome ______________ Sister chromatids These structures at the poles which attach 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 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 Plant _________ cell. animal You can see the cell plate forming in center instead plantof a cleavage furrow. Phase of mitosis in which chromatids separate and move to opposite ends of the cell. anaphase The very first dividing phase prophase in Mitosis: _______________ 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 two: Cytokinesis Name the phases of Mitosis in order: Prophase, Metaphase, Anaphase, Telophase Identify the following phases: 1 2 3 4 5 Identify the following: 2 1 3 Identify the following: 1 2 4 3 5 6 Identify the following: A. Chromosome B. Chromatid C. Centromere D. Chromatin Identify the following: Practice these hand signals for the quiz!!! 1 2 3 4 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) Telophase (T) Metaphase (M) Anaphase (A) 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) Telophase (T) Metaphase (M) Anaphase (A) 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 CYTOKINESIS cells TELOPHASE Spindle fibers and centrioles 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 G2 organelles needed for cell division M _______ Made up of telophase, anaphase, prophase, and metaphase Good luck studying!!
