What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, moving down their concentration gradient.

FLASHCARD QUESTION

Front

What is osmosis?

Back

Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

FLASHCARD QUESTION

Front

What does isotonic mean?

Back

Isotonic refers to a solution that has the same concentration of solutes as another solution, resulting in no net movement of water.
