Cell transport (Biology)

What is the function of the cell membrane?

• To control what can enter or leave the cell

• To protect the cell

• To prevent the cell from exploding

• To produce proteins

Which substance can EASILY cross the phosopholipid bilayer without a transport protein?

• glucose

• water

• oxygen gas

• sodium ion

Diffusion is 

• the movement of a substance from low to high concentration
• a type of transport that involves energy from the cell
• the movement of a substance down its concentration gradient
• the use of membrane vesicles to move substance into the cell

Which direction will water diffuse?

• into the cell
• out of the cell
• it will not move

A person is given pure water directly into their blood. What will happen to the red blood cells?

• the cells will shrink from water loss

• the cells will expand, but the cell wall prevents it from exploding

• the cells will explode due to excessive water uptake
