Question

Why does diffusion occur?

Answer 1

Diffusion:

1. Diffusion is a type of transport that simply occurs when there is a concentration difference where the molecules move from a region of higher concentration to a region of lower concentration.
2. When particles in liquids and gases randomly collide and disperse, diffusion takes place.
3. For living things, diffusion is a crucial mechanism because it governs how molecules enter and exit cells.
4. Because their particles travel swiftly and erratically, gases and liquids are frequently the particles that experience diffusion.
5. In the modern world, diffusion is a crucial process for all living organisms.
6. This is because diffusion allows chemicals to enter and exit cells.
