Diffusion can be described as the process of movement of molecules from a region of higher concentration to a region of lower concentration allowing the entry and exit of substances 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.

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.

What is plant diffusion?

“Diffusion is the process of movement of molecules from a region of higher concentration to a region of lower concentration.” Diffusion in Plants. Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells.

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 are the types of diffusion in geography?

The three main types of this phenomenon are expansion diffusion, stimulus diffusion, and relocation diffusion.

What is difference between osmosis and diffusion?

In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
