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. 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.. 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. . 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.. . 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.. Eukaryotes: organisms with a true nucleus and membrane bound organelles; usually multicellular. Animals, plants, fungi, protists (microorganisms). Eukaryotic cells replicate for growth and development . 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 ________________. . General Biology. Name. ________KEY_______________________. Reproduction. All Cells come from other cells (. Remember the cell theory?. ). Asexual – Organisms formed by only one parent; offspring are identical; fast; fine for environments that don’t change frequently since each organism is a clone. 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..
