Why is diffusion important?
Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow and lets them get rid of waste products.
What are the 3 types of 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 diffusion in your own words?
Diffusion is defined as a spontaneous net movement of particles down their concentration gradient or in other words from an area with greater concentration to the area with lower concentration without using any energy.
What is diffusion in cell?
Molecules can move into or out of cells by the process of diffusion . … Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the molecules.
What is osmosis and diffusion?
Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. … Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
What causes diffusion?
The kinetic energy of the molecules results in random motion causing diffusion. … It is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration. Diffusion will continue until the concentration gradient has been eliminated.
What is diffusion explain with two example?
What are some examples of diffusion in plants?
In order to carry out photosynthesis a plant requires carbon dioxide. On the underside of leaves there are small holes known as stomata carbon dioxide diffuse into the leaves via these. Leaves produce oxygen and water vapour and these in turn diffuse out via the stomata.

Diffusion is when cultural traits of a culture spread to another culture. • Acculturation is when a culture completely transforms and becomes accustomed to the new cultural traits.
What is diffusion Class 12?
Diffusion is the process where gaseous atoms and molecules are moved from regions of comparatively high concentration to regions of comparatively low concentration. Diffusion of gas is inversely proportional to the molecular weight of the gases.
What is diffusion in science class 8?
What is diffusion class 10th?
Answer: Diffusion is the process of movement of molecules under a concentration gradient. … The molecules move from a region of higher concentration to a region of lower concentration until the concentration becomes equal throughout. Liquid and gases undergo diffusion as the molecules are able to move randomly.
What type of diffusion spreads languages?
Language shift can be described as a diffusion process in accordance with physical diffusion—as spread of the dominant language and resulting retreat of the minority language.
Which type of diffusion do we often see in world cities?
Cultural diffusion is the spread of cultural trends across locations. Beliefs practices and ideas get shared from person to person and sometimes even around the world through this diffusion as happens with viral videos. Many cultural practices are spread by a type of cultural diffusion called expansion diffusion.
