explain diffusion and osmos help with examples
Answers
Answer:
Osmosis is a biophysical process occurring commonly in biological systems where solvent molecules move across a semi-permeable membrane towards a region of high solute concentration.

It is a type of passive transport and is directed towards the direction that tends to equalize the solute concentration across a semi-permeable membrane.
It is a common process taking place in most of the biological membrane in the organisms.
In a biological system, the solvent mostly is water; however, osmosis can also take place in other liquids and even gases.
As it is a means of passive transport, it doesn’t require any energy.
Answer:
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.
Examples of Osmosis: Examples include red blood cells swelling up when exposed to freshwater 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.
Explanation:
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.
Examples of Diffusion: Examples of diffusion include the scent of 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.
