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.. 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.. Why Would A Cell Divide?. Growth. Repair. The Cell Cycle, Mitosis, and . Meiosis. New cells can only be made when existing cells divide. All cells have the ability to divide – but some cells lose this ability.. Definition :. Cleavage is a process of rapid and synchronous mitotic cell divisions of the zygote to form numerous cells for building up the offspring’s body . Cleavage differs from other forms of cell division in that it increases the number of cells without increasing the mass.. &. 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:. . KEY CONCEPT . Cells divide during mitosis and cytokinesis.. Show biology presentation film . clip mitosis 2. Chromosomes condense . at . the start of mitosis.. DNA wraps around proteins (histones) that condense it.. 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 :. What limits the size of a cell??. Most cells are between .002 - .2 millimeters. What limits the size of a cell?. Diffusion. Very fast and efficient over short distances. Becomes slow and inefficient as the distances become larger. . 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.. Chapters 12, 13, 16, 17. Limits to Cell Growth. The larger a cell becomes, the more demands a cell places on its DNA. If extra copies of DNA are not made, an “information crisis” would occur. The cell also has more trouble moving nutrients and wastes across the cell membrane. 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. . 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 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. 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 .
