PPT-CHAPTER 12 THE CELL CYCLE

Unicellular organism cell division reproduces an entire organism Multicellular organisms cell division can produce growth or progeny Cell division functions in reproduction growth and repair. Unit 5. Welcome Back! . Musical Chairs. TODAY:. Notes on Cell Cycle. Become medical school students on oncology . rotation. Homework for next time: Watch Bozeman video on cell cycle, mitosis and meiosis. There *may* be a quiz.. Section 5.1. 1. Objectives. SWBAT describe the stages of the cell cycle.. SWBAT compare rates of division in different types of cells.. SWBAT identify factors that limit cell size.. 2. Starter. Why do you always have to cut your hair, your fingernails, and the lawn?. Why do cells need to divide?. Growth and development. You started as 1 cell and now you’re made up of roughly 40 TRILLION cells. Repair and regeneration of tissue. Reproduction. What happens when cells divide? . Cell division creates duplicate offspring in unicellular organisms (Asexual Reproduction). Provides for growth, development, and repair in multicellular organisms (Sexual Reproduction). The cell cycle extends from the creation of a new cell by the division of its parent cell to its own division into two cells. Chapter . 11 (p. 206-213) . Chapter . 12 (p.228-243).

Ways that the cell cycle is regulated.. Ways in which the normal cell cycle is disrupted to cause cancer. . Concept 9.3: The eukaryotic cell cycle is regulated by a molecular control system. 1. Cell Division. The ability of organisms to produce more of their own kind is the one characteristic that best . distinguishes living . things . from nonliving . matter.. Cell division . functions in . Identify and restate what the phases of the eukaryotic cell cycle are.. Restate what happens in each stage of the cycle.. Vocabulary. Cell . cycle. Interphase. Mitosis. Cytokinesis. Cells . Live in a Cycle. . During the cell cycle, a cell grows, prepares for division, and divides to form two identical daughter cells, each. of which then begins the cycle again.. The series of events that cells go through as they grow and divide.. Cell Cycle - a cycle of growth, development, and division. This is how organisms grow, produce new cells, and replace old cells. The cell cycle occurs in 2 phases: Interphase and . Mitosis. The Cell Cycle: Interphase. 1. . Interphase. 2. Cell Division. 2 main parts to the cell cycle. (AKA--Mitotic Phase). C. E. L. L. C. Y. C.

Why is controlling the cycle important?. Complex events must work perfectly to produce new daughter cells. Mutations can occur if events do not go to plan. It is the growth and division of single cell into daughter cells and duplication (replication).. In . prokaryotic cells, . the cell cycle occurs via process termed binary fission..
