Diffusion only takes place ???

Question

is it in living cells?

Answer 1

Diffusion takes place everywhere irrespective of the living cells.They take place in air,water etc; Diffusion is nothing but movement of molecules from a region of higher concentration to a region of lower concentration.

Eg:-

Diffusion is easy to observe, but care must be taken to avoid a mixture of diffusion and other transport phenomena.

It can be demonstrated with a wide glass tubed paper, two corks, some cotton wool soaked in ammonia solution and some red litmus paper. By corking the two ends of the wide glass tube and plugging the wet cotton wool with one of the corks, and litmus paper can be hung with a thread within the tube. It will be observed that the red litmus papers turn blue.

This is because the ammonia molecules travel by diffusion from the higher concentration in the cotton wool to the lower concentration in the rest of the glass tube. As the ammonia solution is alkaline, the red litmus papers turn blue. By changing the concentration of ammonia, the rate of color change of the litmus papers can be changed.

So you can see it takes place everywhere

Answer 2

diffusion takes place everywhere, it's just when something goes from a place of high concentration to low concentration.  For some reason, everything wants to be in equilibrium.  When you open the door on a cold day, the cold air wants to come in and the warm air wants to go out.  Living cells just take advantage of this and use it to get the nutrients they need.
