Question

what is osmosis and mention an example?

Answer 1

Osmosis is the flow of water down its concentration gradient, across a semi-permeable membrane. Osmosis is an example of diffusion, which is when molecules tend to distribute themselves evenly in a space.

Answer 2

a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.This process is called osmosis.
Eg. Plant roots function as a semipermeable membrane, allowing water to infiltrate the roots. The inside of the root contains minerals, sugars and salts dissolved in water; when water is available in the surrounding soil, osmosis causes it to flow through the root wall to its interior.
