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.

What happens to a cell in a hypotonic solution?

Back

The cell gains water and increases in size.

Front

What happens to a cell in a hypertonic solution?

Back

The cell loses water and decreases in size.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent, such as sugar in water.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, such as water.

Front

What is a solution?

Back

A solution is a homogeneous mixture of a solute and a solvent.

Front

How do water molecules move across a cell membrane?

Back

Water molecules can pass through a cell membrane in either direction.

Front

What is equilibrium in the context of osmosis?

Back

Equilibrium is the state where the concentration of solute is equal on both sides of the membrane, resulting in no net movement of water.

Front

What is the role of the cell membrane in osmosis?

Back

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

Front

What is diffusion?

Back

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