Osmosis and Diffusion (N'Dia Vines)

This "gate" on the window is a semi permeable membrane. It is a semi permeable membrane because it only allows certain substances to be transferred into and out the room (cell).

This jar of pickled solution and eggs is an example of osmosis. Osmosis is the movement of water across a semi permeable membrane. In this case, the semi pereamble membrane are the eggs and the pickled solution is moving across the eggs. 

This jar of eggs displays an image of a hypotonic solution. A hypotonic solution is when molecules outside the cell are lower than the concentration in the cytosil. There is more water or pickling solution in this case than food coloring so   it is a hypotonic solution. 

This display of me spraying Glade, shows the vocabulary word Diffusion. Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration without any energy input. I did not have to help the spray spread around the room or push it to come out. The spray spreaded around and reached equilibrium itself without any addition energy. 

This picture of a kool-aid jammer is an example of an hypertonic solution. A hypertonic solution is when molecules outside the cell are higher than the concentration in the cytosol. It is the complete opposite of a hypotonic solution. This kool-aid jammer has more artificial flavoring (solute) than water, so therefore it is a hypertonic solution.
