What is osmosis?

Back

Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration through a selectively permeable membrane.

Front

What does permeable mean?

Back

Permeable means that things can pass through.

Front

What is the process of water moving through a selectively permeable membrane called?

Back

The process is called osmosis.

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Front

What is equilibrium in terms of concentration?

Back

Equilibrium occurs when the concentration of particles inside a cell is the same as the concentration of particles outside the cell.

Front

What is active transport?

Back

Active transport is the movement of particles against their concentration gradient, requiring energy.

Front

What is a selectively permeable membrane?

Back

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

Front

What is the difference between osmosis and diffusion?

Back

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

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell and potentially burst.
