PPT-CELL GROWTH AND DIVISION

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. 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. 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 . All organisms come from one cell. Largest: Ostrich Egg. Smallest: Red Blood Cell. Longest: Nerve Cell . Where do cells come from?. Another cell: . Asexual Reproduction. Exact copy of the cell. A combination of cells:. 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.. Chapter 4: Animal Growth and Heredity. Vocabulary. Life cycle- the stages that a living thing passes through as it grows and changes.. Mitosis- the process by which most cells divide.. Chromosome- A threadlike structure in the nucleus, made up of DNA.. Chapter 10. In Your Notebook. Materials move through cells by diffusion. Oxygen and food move . into cells. , while waste products move out of cells. How does the size of . a cell . affect how . efficiently . 1. Cell Division. The ability of organisms to produce more of their own kind is the one characteristic that best . distinguishes living . things . from nonliving . matter.. Cell division . functions in . Identify and restate what the phases of the eukaryotic cell cycle are.. Restate what happens in each stage of the cycle.. Vocabulary. Cell . cycle. Interphase. Mitosis. Cytokinesis. Cells . Live in a Cycle. 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.. 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. 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. 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 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..
