FLASHCARD QUESTION

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell, leading to cell shrinkage.

FLASHCARD QUESTION

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell, leading to cell swelling.

3.

FLASHCARD QUESTION

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water into or out of the cell.

4.

FLASHCARD QUESTION

Front

What is 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

What is 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 role does energy play in active transport?

Back

Energy is required in active transport to move substances against their concentration gradient.

7.

FLASHCARD QUESTION

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, the cell loses water and shrinks due to the higher concentration of solutes outside the cell.
