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

How long does diffusion last?

Back

Diffusion continues until the concentration of particles in the system is equal.

Front

What is osmosis?

Back

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

Front

During osmosis, what direction does water move?

Back

Water moves from high to low concentration.

Front

What happens to a cell in a high salt concentration solution?

Back

The cell most likely shrinks due to water moving out of the cell.

Front

What is the element symbol for carbon?

Back

The element symbol for carbon is 'C'.

Front

What is a semi-permeable membrane?

Back

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

Front

What is the difference between diffusion and osmosis?

Back

Diffusion involves the movement of all types of molecules, while osmosis specifically refers to the movement of water.

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What happens to a cell in distilled water?

Back

The cell may swell and potentially burst as water moves into the cell.
