  2. 1665- ______________________ used a microscope to examine a thin slice of cork and saw “little boxes” He called them “CELLS” because they looked like the small rooms that monks lived in called Cells Microscope image: http://www.answers.com/topic/microscopeCork image: http://www.cortex.de/img_kork/cork_cells_big.jpg Hooke image: http://www.metaweb.com/wiki/upload/5/5c/Hookeyoungmtwb.jpg

  6. 1855- German medical doctor _____________________ saw dividing cells in the microscope and reasoned that cells come from other cells Virchow: http://www.parlament-berlin.de/Galeriecopy.nsf/0/8ABC720262898739C1256A480037F869?OpenDocument Mitosis: http://biology.dbs.umt.edu/biol101/labs/lab_6_images/sect01and06/Rebecca,%20tanner,%20and%20liam%20mitosis%20root%20tip.jpg

  7. CELL THEORY 1. All living things are ________________________. 2. Cells are the basic unit of ____________ & _____________ in an organism. (cell = basic unit of _____________) 3. Cells come from the reproduction of ____________ cells Cell image: http://waynesword.palomar.edu/lmexer1a.htm

  8. They have different kinds of cells doing different jobs MULTICELLULAR ORGANISM don’t just contain MANY CELLS. Image from: http://www.isscr.org/images/ES-cell-Fig-2.jpg

  9. Cells in a multi-cellular organism become SPECIALIZED by turning different genes on and off Image from: http://www.ncu.edu.tw/~ls/graph/faculty_pictures/whole_time/SLC/SLC_lab-1.jpg Cell Specialization =DIFFERENTIATION
