2. An instrument for magnifying very small objects http://inventors.about.com/library/inventors/blmicroscope.htm

3. The first compound microscope was created by Zacharias Janssen Developed in late sixteenth century Capable of magnifying images: –approximately three times when fully closed –up to ten times when extended to the maximum http://micro.magnet.fsu.edu/primer/museum/janssen.html

4. Cells are alive! All cells come from other cells. All living things are made up of cells… even if it is just one.

8. http://www.martinmicroscope.com/MicroscopePages/Stereomicroscopes.htm Also called dissecting microscopes Made of two compound microscopes which focus on the same point from different angles Low power – cannot see single cells The specimen is viewed in three dimensions The image is upright and laterally correct (not upside down and backwards) http://www.microscope-world.com/images/416-microscope.jpg http://www.umanitoba.ca/Biology/lab1/biolab1 _ 4.html# http://www.ust.hk/~webspade/introduction/Stereomicroscope_eg3.jpg

9. The most commonly used Can view individual cells- even living ones! Image is 2-Dimensional It has high magnification yet low resolution Capable of magnifying images: –32x –100x –400x http://www.southwestschools.org/jsfaculty/Microscopes/compoundscope.html http://www.southwestschools.org/jsfaculty/Microscopes/types.html

11. Images produced with brightfield illumination appear dark and/or highly colored against a bright, often light gray or white, background. http://www.olympusmicro.com/primer/anatomy/brightfieldgallery/index.html http://www.olympusmicro.com/primer/anatomy/brightfieldgallery/bacteriayeastandbloodsmall.html Used for looking at living cells. Dense structures appear darker than the background. Cell structures appear light on a dark background.

14. http://www.bgsu.edu/departments/biology/facilities/MnM/tem.html Transmission Electron Microscope images are created using electrons instead of light Electrons travel at shorter wavelengths than light gives a 2-D view TEM can magnify and resolve a specimen greater than 1,500,000X! It has high magnification and high resolution http://www.sdsmt.edu/es/emes/tem.jpg http://www.udel.edu/Biology/Wags/b617/tem/tem7.gif
