This PowerPoint continues the discussion of Cell Growth and Division and follows my first presentation on Cell Growth and Division. The first presentation included a general introduction on Cell Growth and Division and The Process of Cellular Division. This presentation continues the discussion of cell growth and division with sections three and four: 3.) Regulating the Cell Cycle and 4.) Cell Differentiation. Section 3, Regulating the Cell Cycle, includes topics on the idea of turning genes off and on. A basic discussion of internal and external regulators is included. A basic discussion of cancer is included as well. Section 3, Cell Differentiation, discusses the development of beginning with fertilization. A basic discussion of developmental biology and corresponding terminology is included. A detailed discussion of stem cells wraps up this presentation. This PowerPoint can be used as an excellent review for any end-of-course assessment as well.
