Name: Date: Period: Chapter 3, Lesson 1 Review Sheet Put the steps of the cell cycle in order. 4 3 6 1 5 2 8 7 Prophase G2 Anaphase G1 Metaphase S Cytokinesis Telophase Write MITOSIS or CYTOKINESIS next to the description. Stage of the cell cycle when the nucleus and its contents divide Stage of the cell cycle when the cytoplasm and its contents divide MITOSIS CYTOKINESIS Read the descriptions. Decide if it is describing Interphase, Prophase, Metaphase, Anaphase, or Telophase. Write the correct answer next to it. Chromosomes line up the in single file at the middle of the cell. Copied DNA condenses into chromosomes. METAPHASE A nuclear membrane forms around the chromatin. TELOPHASE Sister chromatids separate; spindle fibers begin to shorten, pulling chromatids towards opposite sides of the cell The nucleolus disappears and nuclear membrane breaks down, spindle fibers begin to form. Includes G1, S, and G2 stages; longest part of the cell cycle; organelles are duplicated Cell begins to lengthen ANAPHASE Spindle fibers begin to break down, two identical nuclei form, chromosomes begin to unwind TELOPHASE PROPHASE PROPHASE INTERPHASE ANAPHASE Answer the following questions. Mitosis and Cytokinesis are part of what phase? What are activities that occur regularly and repeat called? In reference to cells? What is something animals have that plants do not? What is something plants have that animals do not? What do centrioles do in animal cells during mitosis? Reproduction is the result of cell division in what type of organism? If a cell has 34 chromosomes, how many does it have after going through mitosis? What happens to your cells when you become an adult? When cells make exact copies of its DNA, what is it preparing for? What types of cells go through cell division? Do all cells go through the cell cycle at the same rate? What type of cells go through mitosis? Mitotic Phase Do multi-cellular organisms start out as a single cell? Will daughter cells eventually become parent cells? Are daughter cells exact replicas of the parent cells? Yes, start out as a single cell Cycle Cell Cycle Centrioles Cell plates Move to opposite ends of the animal cell and spindle fibers stretch between them Unicellular organisms (one-celled) 34 chromosomes Keep dividing Mitosis All cells (prokaryotic and eukaryotic) No, they do not Eukaryotic cells Yes Yes, genetically identical Label the diagrams on the next page! Label the diagram below. Label the phases of the cell cycle.
