Osmosis

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.

Front

What does hypertonic mean?

Back

A hypertonic solution has a higher concentration of solute compared to another solution, leading to water moving out of cells.

Front

What does hypotonic mean?

Back

A hypotonic solution has a lower concentration of solute compared to another solution, causing water to move into cells.

Front

What does isotonic mean?

Back

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

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain molecules to pass through while blocking others.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will shrink as water moves out of it.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will swell and may burst as water moves into it.

Front

What is the role of the cell membrane?

Back

The cell membrane regulates what enters and leaves the cell, maintaining homeostasis.

Front

What is the process of diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

How does osmosis differ from diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion can refer to the movement of any type of molecule.
