Often asked: What Is The Meaning Of Diffusion In Biology?

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 is the diffusion in biology?

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. The difference in the concentration of a substance between two areas is called the concentration gradient.

What is diffusion biology example?

Examples of diffusion in living organisms oxygen moves down a concentration gradient from the air in the alveoli to the blood. carbon dioxide moves down a concentration gradient from the blood to the air in the alveoli.

What do you mean by 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 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 is diffusion in science class 9?

Diffusion- The mixing of a substance with another substance due to the motion or movement of its particles is called diffusion. It is one of the properties of materials. The diffusion of one substance into another substance goes on until a uniform mixture is formed.

Which is the best definition of diffusion?

Diffusion can be defined as the movement of molecules from an area of their higher concentration to an area of their lower concentration. So, the correct answer is ‘Movement of molecules from an area of their higher concentration to an area of their lower concentration’.

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 the meaning of diffusion in physics?

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.

What is diffusion in biology class 10?

“Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.”

How do you explain diffusion to a child?

Diffusion is a physical process where molecules of a material move from an area of high concentration (where there are many molecules) to an area of low concentration (where there are fewer molecules). Diffusion usually happens in a solution in gas or in a liquid.

What is meant by diffusion in sociology?

Diffusion, also known as cultural diffusion, is a social process through which elements of culture spread from one society or social group to another, which means it is, in essence, a process of social change.

Why is diffusion important in biology?

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.
