Worksheet on passive and active transport
A cell placed in salt water shrinks. What type of solution is salt water?
Looking at the diagram, what type of transport is used to move oxygen (O2)
Moves small molecules from high to low concentration using transport proteins
involves water moving across the plasma membrane to the side with greater solute concentration (less water)
Occurs when substances move against the concentration gradient. Requires energy and the aid of carrier proteins
occus when the plasma membrane surrounds a large substance inside the cell and moves it outside the cell
occurs when the plasma membrane surrounds a large substance outside the cell and moves it inside the cell
a solution that has the same osmotic concentration as a cell's cytoplasm
a solution that causes a cell to shrivel or shrink in size
a solution that causes a cell to swell
a solution that neither shrinks nor swells a cell
a solution in which there is more water outsides the cell than inside the cell. Water enters the cell
a solution that causes water to move out of a cell
Name the two transport processes that allow large substances to cross the plasma membrane
Identify three transport process in cells that do not require energy
Match the description to the correct type of membrane transport
No energy
moves from high to low
moves from low to high
needs energy
Active Transport
Passive Transport
Looking at the diagram, what type of transport is used to move sodium (Na+)
Looking at the diagram, what type of transport is used to move water (H2O)
Explain the difference between diffusion and active transport.
