a. A human cell is placed in a container of sugar water. Explain what would occur, if the cell membrane is impermeable to sugar.

b. Another cell is placed into a container of sugar water. However, this cell has the capability to allow large molecules such as sugar to pass through. What will occur in this cell when it is placed into the container of sugar water?

c. If you were yo use a really powerful microscope what might you notice about this cell membrane compared to the first one?

d. At first the passage of sugar across the membrane in the cell from Letter B occurs very slowly, but then the sugar starts to pass at a a very fast rate until the balance of sugar in the cell and outside the cell is reached. What caused this to happen, and what is the name given to this process?
