Cell Transport Classwork

The process by which water molecules go from a high concentration to a low concentration is called

• solubility

• solubility

• Osmosis

• 
  endocytosis

The ability for a cell membrane to allow certain things in and out allows it to maintain its

• evolution

• homeostasis

• integrity

• independence

Molecules move in and out of a cell by diffusion. The picture shows a cell and molecules both inside and outside the cell.

How will the molecules in this illustration move as a result of diffusion?

• out of the cell

• into another cell

• to the external environment

• into the cell

More water outside of the cell.

Water will move in what direction?

Hint: high ---> _____

• move into cell

• move out of cell

In the image, the water will move 

• into the cell.
• out of the cell.
• both in and out of the cell.

During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will

• 
  move across the membrane to the outside of the cell.

• stop moving across the membrane.

• continue to move across the membrane in both directions.

• 
  move across the membrane to the inside of the cell.

In an isotonic solution

• there is more solute outside of the cell and water moves out/cell shrinks

• there is an equal amount of solute inside and outside of the cell/cell remains the same

• there is less solute outside of the cell and water moves into the cell/cell swells

• 
  the cells are turgid

In a hypertonic solution

• there is more solute outside of the cell and water moves out/cell shrinks

• there is an equal amount of solute inside and outside the cell/cell remains the same

• there is less solute outside of the cell and water moves into the cell/cell swells

• 
  the cell is turgid

In a hypotonic solution the following

• there is more solute outside of the cell and water moves out/cell shrinks

• 
  there is an equal amount of solute inside and outside the cell/cell remains the same

• 
  there is less solute outside of the cell and water moves into the cell/cell swells

• none

The sodium potassium pump in muscle cells pushes sodium and potassium molecules against the concentration gradient.  This is an example of 

• passive transport

• equilibrium

• 
  osmosis

• active transport
