C. ___________________
3. The main method of Cell Transport is ______________.
4. ____________ is the process by which molecules move from a high concentration
to a low concentration. Give 3 examples.
5. __________ is the diffusion of water molecules.
6. Both ____________ and __________ are examples of ________ transport
because the do NOT require energy.
7. When a red blood cell has it’s normal doughnut shape, the concentration of water in
the solution around the cell is the ______ as inside the cell.
8. In the concentration of water is lower than inside the cell, so water ________ the
cell, causing the cell to _______.
9. In , The solution surrounding the cell has more water than the inside of the cell, so
water _________ the cell, causing it to ________.
