FLASHCARD QUESTION

Front

What is simple diffusion?

Back

Simple diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration without the use of energy or transport proteins.

2.

FLASHCARD QUESTION

Front

What happens to a cell in a hypotonic solution?

Back

A cell in a hypotonic solution will swell and may burst (lyse) due to the influx of water.

3.

FLASHCARD QUESTION

Front

What is active transport?

Back

Active transport is the movement of particles against their concentration gradient, requiring energy (usually in the form of ATP).

4.

FLASHCARD QUESTION

Front

What occurs to a freshwater fish cell in saltwater?

Back

The cell would shrivel because the saltwater solution is hypertonic, causing water to leave the cell.

5.

FLASHCARD QUESTION

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of transporting molecules across a cell membrane via protein channels, without the use of energy.

6.

FLASHCARD QUESTION

Front

Define osmosis.

Back

Osmosis is the diffusion of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

7.

FLASHCARD QUESTION

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to another solution, leading to water moving out of cells placed in it.
