FLASHCARD QUESTION

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

2.

FLASHCARD QUESTION

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration until equilibrium is reached.

3.

FLASHCARD QUESTION

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy (ATP).

4.

FLASHCARD QUESTION

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically along the concentration gradient.

5.

FLASHCARD QUESTION

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing the cell to shrink.

6.

FLASHCARD QUESTION

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing the cell to swell and potentially burst.

7.

FLASHCARD QUESTION

Front

What is an isotonic solution?

Back

An isotonic solution has the same solute concentration as the inside of the cell, resulting in no net movement of water.
