What are the 3 different types of diffusion?
The three types of diffusion are – simple diffusion, osmosis and facilitated diffusion.
- (i) Simple diffusion is when ions or molecules diffuse from an area of high concentration to an area of low concentration.
- (ii) In osmosis, the particles moving are water molecules.
What is meant by term diffusion?
Diffusion is defined as the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration (34).
What are 3 examples of cultural diffusion?
Common Cultural Diffusions For example, jazz started as a blend of the music of Africa and the Caribbean. Southern cities in the United States, especially border towns, have signs in both English and Spanish. The popularity of sushi, a traditional Japanese dish, shows diffusion of Japanese cuisine.

What is diffusion GCSE?
Diffusion is the random movement of a substance from a region of high concentration to a region of low concentration (ie: down the concentration gradient). For example, oxygen moves from a high concentration in the lungs to a low concentration in the blood.

What is diffusion explain?
diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room. ion diffusion across a semipermeable membrane.
What is diffusion in living environment?
Both living and nonliving systems experience the process of diffusion. In living systems, diffusion is responsible for the movement of a large number of substances, such as gases and small uncharged molecules, into and out of cells.
What is diffusion Wikipedia?
"Diffusion" is the gradual movement/dispersion of concentration within a body, due to a concentration gradient, with no net movement of matter. An example of a process where both bulk motion and diffusion occur is human breathing. First, there is a "bulk flow" process.
What are the five types of diffusion?
Relocation, expansion, contagious, hierarchical, and stimulus diffusion.
What is diffusion short answer?
Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration . Diffusion occurs in liquids and gases when their particles collide randomly and spread out. Diffusion is an important process for living things – it is how substances move in and out of cells.
What are 5 examples of diffusion?
Some examples of diffusion that occurs in our daily life are given below.
- The smell of perfumes/Incense Sticks.
