Diffusion and Osmosis

Front

What is diffusion?

Back

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

Front

What is osmosis?

Back

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

Front

What does 'high concentration area' mean?

Back

A high concentration area refers to a space where molecules are tightly packed together.

Front

What happens to cells in a hypotonic solution?

Back

Cells will expand or swell because water moves into the cell.

Front

What happens to cells in a hypertonic solution?

Back

Cells will shrink or dehydrate because water moves out of the cell.

Front

What is a semi-permeable membrane?

Back

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

Front

What is the role of concentration gradient in diffusion?

Back

The concentration gradient is the difference in concentration between two areas, and it drives the movement of molecules during diffusion.

Front

Can diffusion occur in solids?

Back

Yes, diffusion can occur in solids, but it happens much more slowly compared to liquids and gases.

Front

What is an example of diffusion in everyday life?

Back

An example of diffusion is the smell of perfume spreading in a room.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion refers to the movement of any molecules, while osmosis specifically refers to the movement of water.
