8                                                                                                                                                                ______________________________________________________________________________ HOW CELLS REPRODUCE Chapter Outline IMPACTS, ISSUES: HENRIETTA'S  IMMORTAL CELLS OVERVIEW OF CELL DIVISON   MECHANISMS Mitosis, Meiosis, and the Prokaryotes Key Points About Chromosome Structure INTRODUCING THE CELL CYCLE The Wonder of Interphase Mitosis and the Chromosome Number A CLOSER LOOK AT MITOSIS DIVISION  OF THE CYTOPLASM Cleavage in Animals Cell Plate Formation in Plants Appreciate the Process! WHEN CONTROL IS LOST The Cell Cycle Revisited Checkpoint Failure and Tumors Characteristics of Cancer SUMMARY SELF-QUIZ CRITICAL THINKING Objectives 1. Understand  the factors that cause cells to reproduce. 2. Understand  what  is meant  by  cell cycle  and  explain where mitosis fits into the cell cycle. 3. Be able to describe each phase of mitosis. 4. Explain  how  the  apportioning  of cytoplasm  to the  daughter  cells follows  mitosis, which  is a  nuclear event. 5. List some the problems in cell division when  control is lost. Key Terms mitosis somatic cells meiosis germ cells chromosome sister chromatids histones nucleosome 58 Chapter  Eight

Lecture Outline Henrietta’s Immortal Cells A. Researchers at Johns Hopkins cultured  a line of immortal cells in 1951. 1. They are referred  to as HeLa cells after their source—a woman  named  Henrietta  Lacks. 2. Her cells continue  to provide  for research around  the world. B. Understanding  cell division starts with three questions.
