Cell Transport HW

___ is particle movement from an area of lower concentration to an area of higher concentration.

• Active transport

• Passive transport

Which type of passive transport focuses on the movement of water through the membrane?

• Facilitated diffusion

• Osmosis

• Diffusion

What term describes a solution that has the same solute concentration inside of and outside of the cell?

• Hypertonic

• Hypotonic

• Isotonic

The cell shrunk in size, which means it was placed in a ____ solution.

• Isotonic

• Hypertonic

• Hypotonic

In which case would a cell most likely shrink?

• when placed in a solution containing a high salt concentration
• when placed in a isotonic solution
• when placed in a solution containing a low pH
• when placed in a solution containing distilled water

Active transport requires energy because...

• The cell is moving something against a concentration gradient
• The cell is moving something with a concentration gradient
