Understanding Diffusion Concepts

Front

What is DIFFUSION?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

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 ACTIVE TRANSPORT?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is an ISOTONIC solution?

Back

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

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 difference between diffusion and osmosis?

Back

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

What is the role of temperature in diffusion?

Back

Higher temperatures increase the energy of molecules, causing them to move faster and diffuse more quickly.
