Definition of diffusion class 9. Diffusion is the process of movement of any substance from a region of higher concentration to a region of lower concentration. Diffusion is widely used in various fields such as biology physics chemistry etc. Simple diffusion a process in which the substance moves through a semipermeable membrane or in a solution without any help from transport proteins. The particles will mix until they are evenly distributed.
Diffusion is the movement of particles from higher to lower concentration. Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. Diffusion may also be thought of as the movement of particles down a concentration gradient. Find out more in this bitesize science video for ks3.
Similarly the medium in which diffusion occurs could also be in one of the three physical states. Class 9 biology q1 a differentiate between diffusion and osmosis. Simple diffusion and facilitated diffusion. The student sitting next to you just came from gym class and forgot to shower and you can tell.
Diffusion is a result of the kinetic properties of particles of matter. 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. B on the basis of your understanding of movement of molecules write osmosis or diffusion in the examples below. This document is highly rated by class 9 students and has been viewed 8883 times.
The material that diffuses could be a solid liquid or gas. The movement of gases like carbon dioxide and oxygen from a region of high concentration to a region of low concentration through a semi permeable membrane is known as diffusion.
