PPT-Cell Division and Cancer

Unit 7 Mitosis Mitosis All cells in your body divide In children and teens cells divide to assist in growth In adults cells divide to replace old cells Your cells are really good at knowing when they should and shouldnt divide. Presented by: . N. avdeep. . K. aur. . . Apoorva. . Tandon. M.Sc.(Foods and Nutrition)3. rd. sem.. Contents…. Introduction. Biology of cancer. Causes of cancer. Factors increasing cancer risk. A Disease of Mitosis. 1. Cancer: a Disease of Mitosis. Cancer is a . disease of . mitosis – resulting in uncontrollable mitotic division.. Cells do not live forever, and they will reach a point where they will . 2.5.1: Cell . Cycle: Outline the stages of the cell cycle, including . interphase. (G1, S, G2), mitosis and . cytokinesis. Cytokinesis starting. *During . its life, a cell passes through a well-ordered series of events known as the . 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? . &. Cellular Division. I. Cell Division:. . All . cells. are derived from preexisting cells (Cell Theory) . Cell division . is the process by which cells produce new cells . I. Cell Division:. . Cell Division . —. . process by which a cell divides into . 2 new cells. Why do cells need to divide? . Living things . grow. by producing . more cells. , NOT because each cell increases in size. to the cell theory: all cells come from preexisting cells. . Why, when and how . cells divide is the subject of this unit..  . Reproduction. Cells reproduce in order to make new cells.. A bacterium divides to become two bacteria.. Chapter 10. Limits to Cell Size. Cells grow as the organism grows.. However cells only grow to a certain extent then divide. Why?. . - The larger the cell the more demands on its . dna. . - a large cell has more trouble moving food in and waste out. Chapter 10. In Your Notebook. Materials move through cells by diffusion. Oxygen and food move . into cells. , while waste products move out of cells. How does the size of . a cell . affect how . efficiently . Topic 1: DNA Organization. By the end of this topic, you should be able to…. Identify parts of a chromosome. Explain why DNA has to copy and coil before cell division. Explain why cells cannot continue to grow forever. 1. Grab the chromosomes from the. parent cell . to fill in the other steps in mitosis, including . DNA replication. , . cell division. and the resulting two . daughter cells. . . 2. Answer the question below and move to the next slide.. ANA 205. 2. Differentiation. - development of a fertilized egg cell to form a complex, multicellular organism involving cellular replication, growth and progressive specialization for a variety of functions. . Acknowledgement. I would like to express special thank of gratitude to our respected principal madam, Mrs. . Kuljit. . Kaur. , for giving us this unique opportunity to express ourselves in a creative way. 1. Cell division. Mitosis. Cell division functions in reproduction, growth, and repair. In unicellular organisms, the division of one cell to form two reproduces . an entire . organism (e.g., bacteria, yeast, .
