Types of cell transport

Front

What is osmosis?

Back

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

Front

What does it mean for a solution to be hypertonic?

Back

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

Front

What does it mean for a solution to be hypotonic?

Back

A hypotonic solution has a lower concentration of solutes compared to another solution, causing water to move into a cell placed in that solution.

Front

What does it mean for a solution to be isotonic?

Back

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

Front

What happens to a plant cell in a hypertonic solution?

Back

The plant cell will lose water, causing it to become plasmolyzed and wilted.

Front

What happens to a plant cell in a hypotonic solution?

Back

The plant cell will gain water, becoming turgid and maintaining its rigidity.

Front

What is the role of the cell membrane in osmosis?

Back

The cell membrane is selectively permeable, allowing water to pass through while restricting the movement of certain solutes.

Front

What is diffusion?

Back

Diffusion is the movement of solute particles from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

How does osmosis differ from diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of solute particles.

Front

What is plasmolysis?

Back

Plasmolysis is the process where a plant cell loses water in a hypertonic solution, causing the cell membrane to pull away from the cell wall.
