PPT-Cell Division—Mitosis Notes

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. 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.. Notebook Page 12. Warm . Up & Spiral. 2/23/2017. What is the chemical formula for glucose? . How many hydrogen atoms are in glucose? . What is protein synthesis? . OBJECTIVES: 8.L.5.1. -TSWU that cells carry on the many functions needed to support life including cell respiration, photosynthesis, protein synthesis, mitosis, and meiosis. . 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 . Parts of the Human Cheek Cell at 40X Magnification. Can you name these parts of the Human Cheek Cell?. CELL CYCLE. D. uring Interphase DNA replicates which must occur before Mitosis can begin .. Centrioles. 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.. How did I grow taller. ?. . How . are my worn out cells replaced. ? . How . do I heal from injuries. ?. The answer is….. Cellular Reproduction . or Mitosis. THE . CELL CYCLE:. Cells go through cycles during their lifetime.. Figure 12.1b The functions of cell division: Growth and development. Figure 12.1c The functions of cell division: Tissue renewal. Figure 12.2 Eukaryotic chomosomes. Figure 19.0 Chromatin in a developing salamander ovum. Chromatin – the less tightly coiled DNA-protein complex. Centromere – the region of the chromosome that holds the two sister chromatids together during mitosis.. SEX CHROMOSOMES & AUTOSOMES. Sex chromosomes are chromosomes that determine the sex of an organism, and they may also carry genes for other characteristics. . The . cell cycle. is a repeated pattern of growth and division that occurs in eukaryotic cells. . This cycle consists of three phases: G1, S, G2. The first phase represents cell growth while the last two phases represent cell division.. Standard: . recognize the significance of meiosis to sexual reproduction. . . [. BIO.6G. ]. describe the stages of the cell cycle, including deoxyribonucleic acid (DNA) replication and mitosis, and the importance of the cell cycle to the growth of organisms. Learning objective This learning material is about the life cycle of a cell and the series of stages by which genetic materials are duplicated and partitioned to produce two daughter cells with the 172BIOLOGY CELL CYCLE AND CELL DIVISION171 The stages through which a cell passes from one division to the next is calledthe cell cycle. Cell cycle is divided into two phases called (i) Interphase
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).
