PPT-CYTOKINESIS Division of the cell

Means to move the cell Approximately 5 of cells life Process differs in Heterotrophs Animals Autotrophs Plants due to presence of cell wall HETEROTROPHS AUTOTROPHS Cell membrane . The Only Time When Division and Multiplication Will Mean The Same Thing!. The Life of a Cell. All cells in your body alternate between two different activities.. Interphase. – the cell is doing the job it was meant to do and/or preparing for cell division.. . Repair and Growth. Reproduction. Asexual. : process in which a single cell or set of cells produces offspring that inherit all their genetic material from one parent . Sexual. : process in which genetic material from two parents combines and produces offspring that differ genetically from either parent . Cell Division. Remember…. *DNA more stable than RNA. * All organisms must be able to reproduce to keep life going. One cell becoming . two. All Reproducing Cells. 1. Replicate DNA in parent cell during the S phase.. Efficiency . Smaller the cell = quicker it can work. Transport of Substances. Cellular communication. Ratio of surface area to volume. Other reasons for cellular division. Growth. Replace damaged cells. &. 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:. . The features of mitosis that result in the production of genetically identical daughter cells. . The Cell Cycle. Cytokinesis. Mitosis. S. (DNA synthesis). G. 1. G. 2. Figure 9.1 – Chromosomes during cell division. 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. CELL CYCLE. . The . sequence of events by which a cell duplicates its genome, synthesis the other constituents of the cell and eventually divides into two daughter cells. .. Phases of cell cycle :. •Interphase :. . 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.. 1 Cell Cycle is an orderly sequence of events by which a growing cell duplicates its contents and divides into two. The period required to complete one cell cycle is called generation time, e.g., 20 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. For growth and repair. To get food, water, and waste in and out of our bodies quickly. What is the Cell Cycle?. Series of events that take place from one cell division to the next. Constantly repeated. Chromatin. - unwound DNA (loose). . Copied. Sister chromatids. - two identical copies of DNA (loose). . Coiled and Connected. Chromosomes. - two coiled, identical copies of DNA connected to each other (tight). mitosis. results in an increase in number of . identical. cells for . growth and repair. .. Identify and name the stages of mitosis in diagrams and photomicrographs.. Describe the . cell cycle. and relate it to an understanding of .
