​

Answer 1

Explanation:

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.

Answer 2

Answer:

Students are often asked to explain the similarities and differences between osmosis and

diffusion or to compare and contrast the two forms of transport. To answer the

question, you need to know the definitions of osmosis and diffusion and really

understand what they mean.

Osmosis And Diffusion Definitions

Osmosis: Osmosis is the movement of solvent particles across a semipermeable

membrane from a dilute solution into a concentrated solution. The solvent moves to

dilute the concentrated solution and equalize the concentration on both sides of the

membrane.

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.

Osmosis And Diffusion Examples

Examples of Osmosis: Examples of osmosis include red blood cells swelling up when

exposed to fresh water and plant root hairs taking up water. To see an easy

demonstration of osmosis, soak gummy candies in water. The gel of the candies acts as a

semipermeable membrane.

Examples of Diffusion: Examples of diffusion include perfume filling a whole room and

the movement of small molecules across a cell membrane. One of the simplest

demonstrations of diffusion is adding a drop of food coloring to water. Although other

transport processes do occur, diffusion is the key player.
