Diffusion & Osmosis

Front

What is diffusion?

Back

Diffusion is the process where molecules move from an area of high concentration to an area of low concentration.

Front

What happens during osmosis?

Back

During osmosis, water moves from an area of high concentration to an area of low concentration.

What occurs to an animal cell in a hypertonic solution?

Back

An animal cell placed in a hypertonic (salty) solution will shrink and get smaller.

Front

Where is there a low concentration of dye in a cup?

Back

There is a low concentration of dye at the bottom of the cup.

Front

What is osmosis?

Back

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

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of a cell, causing the cell to lose water.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of a cell, causing the cell to gain water.

Front

What is isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of a cell, resulting in no net movement of water.

Front

What is concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance between two areas.

Front

What is semi-permeable membrane?

Back

A semi-permeable membrane is a barrier that allows certain molecules to pass through while blocking others.
