What is a simple definition of osmosis?
What is a simple definition of osmosis?
osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes).
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 difference between diffusion and osmosis?
Osmosis is the movement of solvent particles from a solution that is diluted to a more concentrated one. In contrast, diffusion is the movement of particles from a higher concentration region to a region of lower concentration.
What is diffusion in biology simple definition?
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 kid definition?
Kids Definition of diffusion 1 : the act of spreading or allowing to spread freely. 2 : the mixing of particles of liquids or gases so that they move from a region of high concentration to one of lower concentration.
What is osmosis Class 9?
Osmosis is the movement of water molecules or a solvent from a region of low water concentration towards a region of high water concentration of solute through a semi-permeable membrane. Osmosis is a vital process in biological systems, which occurs in liquids, supercritical liquids and gases.
What do you mean 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 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 is diffusion and osmosis Class 9?
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.
What is osmosis diagram?
Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution (high concentration of water) to a concentrated solution (low concentration of water). In the diagram, the concentration of sugar is initially higher on the right side of the membrane.
What is osmosis Class 10?
“Osmosis is a process by which the molecules of a solvent pass from a solution of low concentration to a solution of high concentration through a semi-permeable membrane.” Osmosis.
What is diffusion Class 9 short answer?
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. Diffusion takes place in gases, liquids and solids.
