What happens to a cell in a hypertonic solution?

Back

The cell shrinks.

Front

What are organelles?

Back

Tiny cell structures that carry out specific functions within the cell.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What is an isotonic solution?

Back

A solution where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What is the role of the cell membrane?

Back
