What is osmosis & 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 is a diffusion easy definition?
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. diffusion. noun.
Why is osmosis considered a special case of diffusion?
This means osmosis is a special case of diffusion: the diffusion of water. This is because the selectively permeable membrane lets water molecules pass through much more rapidly than it lets sugar molecules pass through.
What is the work of diffusion?
Diffusion is the process of movement of molecules under a concentration gradient. Diffusion helps in the movement of substances in and out of the cells. The molecules move from a region of higher concentration to a region of lower concentration until the concentration becomes equal throughout.
When does the diffusion of responsibility take place?
Bystander effect is when individuals are least likely to come to the aid of others when there are bystanders present (Schneider, Gruman & Coutts, 2012). The theory of the diffusion of responsibility runs hand-n-hand with the bystander effect in that when circumstances occur and there are many individuals nearby,…
What is the definition of diffusion in chemistry?
Diffusion Definition. “Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.”. Read on to explore what is diffusion and the different types of diffusion.
Where does diffusion occur in the cell membrane?
Diffusion is the way of passive transport of substances in and out of the cell across the cell membrane. Diffusion occurs down the concentration gradient, i.e. from higher concentration to lower concentration.
Why is diffusion important to all living organisms?
9. State the significance of diffusion. Diffusion is a very important process occurring in all living beings. All living organisms exhibit one or the other form of diffusion, allowing the movement of the molecules during various metabolic or cellular processes.
