Cell Transport Midterm Exam Questions
Solved Correctly.
Passive Transport - Answer molecules move with the concentration gradient from high to low
concentration NO energy required.
Diffusion - Answer Movement of MOLECULES from area of high concentration to an area of low
concentration. (small molecules move this way)
Osmosis - Answer Diffusion of WATER through a semipermeable membrane from a place of higher
concentration to a place of lower concentration until the concentration on both sides is equal.
Hypertonic solution - Answer Environment outside of the cell has more dissolved material than the
inside of the cell. Concentration of solutes (particles other than water - sugar, salt, etc.) outside the cell is
higher than the concentration inside the cell; this will cause the net movement of water molecules to
move out of the cell. Cell will shrink in size - dehydrate.
Hypotonic solution - Answer Environment inside of the cell has more dissolved material than the
outside of the cell. Concentration of solutes (particles other than water - sugar, salt, etc.) outside the cell
is lower than the concentration inside the cell; this will cause the net movement of water molecules to
move inside of the cell. Cell can swell and burst if too much water moves in.
Isotonic solution - Answer The amount of dissolved materials is equal on both the inside and outside of
the cell. Concentration of solutes outside the cell equals the concentration inside the cell. Cell will stay
the same size.
Facilitated Diffusion - Answer Use of carrier PROTEINS for diffusion, does not require energy for a
molecule to travel across the membrane.
Moves molecules from high to low solute concentration.
Active Transport - Answer When energy is used to transport molecules across the membrane against
the concentration gradient.
