Cellular Transport Test

Active Transport requires energy to get molecules across the cell membrane. This energy is required because the movement is ________.

• with the concentration gradient

• against the concentration gradient

Match the following:

• Cell will remain the same

• Isotonic

• Cell will swell

• Hypotonic

• Cell will shrink

• Hypertonic

Diffusion happens because​ (a)  

• molecules are constantly moving
• molecules are never moving

An animal cell that is surrounded by fresh water will burst because ​ (a)   will move ​ (b)   the cell.

• water
• into
• Solutes
• out

• hypertonic

• hypotonic

• osmotic

Locate a Channel protein in the cell membrane.

When the concentration of molecules on both sides of the cell membrane are the same, the molecule will ___

• Move across the membrane in both directions equally.

• move from the inside to the outside of the cell only.

• stop moving completely.

• move form the outside to the inside only.

The diffusion of water across a selectively permeable membrane is called ​ (a)
