Question

diffusion and osmosis, when cells kf carrots, onions or potatoes are places in a solution of salt water, what happens to the cells ?

Answer 1

-Putting a carrot in salty water will make it shrivel up, as water leaves the carrot's cells to enter the salty water this process is called osmosis.
- In potato and onion case also same A large number of salt entered the cells of the potato,more water exits the cells (like in the hypertonic solution) causing the cells to snivel or die causing the potato to shrink .

Definition
osmosis :-
Osmosis is the movement of water through a semi permeable membrane from a region of high concentration to a region of low concentration, tending to equalise the concentrations of the water.

Diffusion -
Diffusion is the net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It continues until the concentration of substances is uniform throughout.
