The lower half of Mr. Andersen's head explains why cells are small. This video begins with a simple geometry problem and ends with a discussion of Allen's Rule and reasoning for the microscopic nature of cells.
By: Cellbiophysics
Erythrocytes (top) and leukocytes (bottom) subjected to a cyclic osmotic change (from isotonic to hypertonic, back to isotonic and finally to hypotonic - distilled water). When exposed to hypertonic solution, the cells shrink. When exposed to water, they swell and burst - erythrocytes become "ghosts" (they expel hemoglobin and lose contrast) and leukocytes blow up like popcorn (see http://youtu.be/Yf_vo4RQThs).
Did you miss seeing the yeast during the microscope lab?? Well, here you go!
