7. CELL THEORY the ideas of Schleiden, Schwann, and Virchow. The cell theory consists of three principles: 2. All organisms are ________________________ 1.Cells are the basic units of _____________. 3. Cells arise from ____________ cells. Cell image: http://waynesword.palomar.edu/lmexer1a.htm made of one or more cells. existing all life

8. CELLS DIFFER IN : Size Shape Function

9. CELL SIZE Typical cells range from: 5 – 50 micrometers (microns) in diameter http://facstaff.bloomu.edu/gdavis/links%20100.htm

10. How big is a micron ( µ ) ? http://www.talentteacher.com/pics/005cb.jpg 1 cm = 10,000 microns 1” = 25,000 microns

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

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

13. Cells in a multi-cellular organism become SPECIALIZED Image from: http://www.ncu.edu.tw/~ls/graph/faculty_pictures/whole_time/SLC/SLC_lab-1.jpg Cell Specialization =DIFFERENTIATION
