What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to another solution, causing water to move into cells, leading to cell swelling or bursting.

What is an isotonic solution?

Back

An isotonic solution has an equal concentration of solutes compared to another solution, resulting in no net movement of water into or out of cells.

FLASHCARD QUESTION

Front

Define passive transport.

Back

Passive transport is the movement of particles across a cell membrane from an area of high concentration to an area of low concentration without the use of energy.

5.

FLASHCARD QUESTION

Front

Define active transport.

Back

Active transport is the movement of particles across a cell membrane from an area of low concentration to an area of high concentration, requiring energy.

6.

FLASHCARD QUESTION

Front

What is diffusion?

Back

Diffusion is the process by which particles spread from an area of high concentration to an area of low concentration.
