PPT-Cell Division—Mitosis Notes

EQ How do cells divide 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. 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 . Cytokinesis. 01-08-09. http://www.cellsalive.com/mitosis.htm. Cell Division. The division of eukaryotic cells occurs in two main stages. Mitosis is the first stage. Is the process by which the nucleus of the cell is divided into two nuclei, each with the same number and kinds of chromosomes as the parent cell. Mitosis. History . of Understanding Cancer. Rudolf Virchow (1821-1902) – First to recognize leukemia in mid-1800s, believing that diseased tissue was caused by a breakdown within the cell and not from an invasion of foreign organisms.. A Chromosome and Sister Chromatids. Key Points About Chromosome Structure. A . chromosome consists of DNA that is wrapped around proteins (. histones. ) and condensed. Each . histone. and the DNA wrapped around it make up a . Cell Division . —. . process by which a cell divides into . 2 new cells. Why do cells need to divide? .

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.. 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. . The _____________ _____________ is a series of steps that cells go through to ____________ and ___________. It can be split into three distinctive processes: ________________, mitosis and ___________________. The first process can be broken down into three distinctive sub-phases. During ____________ and ____________ the cell is carrying on normal cell functions like growing and producing proteins. However, during _____________ the cell’s _____________ is replicated. The cell cycle has _______________ along the way to make sure cells are not reproducing incorrect versions of themselves. In rare occurrences damaged or abnormal cells can get copied which can lead to ______________ or ________________. . There are certain cells that do NOT divide: . Brain. Nerve. Muscle (after reaching adult size). Remember . IPMATC. (. I. . P. ray . M. ostly . A. t . T. he . C. hurch). Cell divides to make TWO identical cells. . Unicellular organisms. cell division = reproduction. Multicellular organisms. cell div. needed for development. & for reproduction (meiosis). Mitosis gives each cell. complete set of genetic material. 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 . Mitosis PAG 1.1. Foundations in Biology. spec. Mitosis and Cell Cycle. Learning Objectives. - Collection and presentation of data:. • Produce a root tip squash;. • Use a light microscope to produce annotated drawings of the stages of mitosis..
