DRAW A PICTURE SHOWING WHAT ENTERS YOUR CELLS AND WHAT LEAVES YOUR CELLS: WEBSITE #4: http://www.wiley.com/legacy/college/boyer/0470003790/animations/membrane_transport/membrane_transport.htm CLICK ON DIFFUSION AND OSMOSIS 1. Molecules always like to move from regions of _____________ concentration to regions of _____________concentration. CLICK “CONTINUE” SO YOU CAN SEE THE MOLECULES MOVE! 2. What happened in the animation. EXPLAIN. WEBSITE #5: http://programs.northlandcollege.edu/biology/Biology1111/animations/transport1.html CLICK ON “PASSIVE TRANSPORT” 1. Does PASSIVE TRANSPORT require ENERGY for your cells? __________ 2. What are THREE TYPES of PASSIVE TRANSPORT? a. b. c. NOW LOOK AT THE BOTTOM OF THE BOX, IN THE YELLOW BAR, CLICK ON “SIMPLE” 1. What is DIFFUSION? What happened in the animation? Draw how the molecules moved: BEFORE AFTER WEBSITE #6: http://www.wisc-online.com/objects/index_tj.asp?objID=AP1903 YOU WILL HAVE TO GO A FEW SLIDES IN….CLICK ON "RAISED" and then "LOWERED" 1. Does diffusion happen FASTER or SLOWER if the TEMPERATURE is RAISED?
