  1. 7-4 The Diversity of Cellular Life

  2. All living things made of cells BUT… organisms can be very different. Image from: http://www.agen.ufl.edu/~chyn/age2062/lect/lect_06/bacsiz.GIF UNICELLULAR MULTICELLULAR http://www.angelbabygifts.com/ http://www.inclusive.co.uk/downloads/images/pics2/tree.gif

  3. 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

  4. 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

  5. Ex: SPECIALIZED ANIMAL CELLS Red blood cells Muscle cells http://www.biologycorner.com/bio3/images/bloodcells3D.jpg Cheek cells http://www.mlms.logan.k12.ut.us/~ajohnson/Cells.html

  6. Ex: Specialized Plant cells Guard cells Xylem cells Pollen Guard cells: http://botit.botany.wisc.edu/courses/img/Botany_130/Diversity/Bryophytes/Anthoceros/Guard_cells.jpg Xylem: http://botit.botany.wisc.edu/images/130/Secondary_Growth/Woody_Stems/Tilia_Stem/Secondary_Growth/One_Year_Stem/Primary_xylem_MC.jpg Pollen: http://www.uic.edu/classes/bios/bios100/labs/pollen.jpg
