In a hypotonic solution, what way does water move?

In a hypotonic solution, water moves into the cell by endosmosis.


Tonicity is actually a phrase which explains the mode of concentration of a certain solution in terms of hypertonicity, hypotonicity or isotonicity.

Hypotonic solution is the one which has a comparatively lesser concentration of solutes in the solution with respect to the surrounding solution.

So, it is quite obvious that the flow of water will be towards the hypertonic solution, in order to bring about isotonicity.

Now, if the surrounding solution is hypotonic then, water flows in by endosmosis , & if surrounding solution is hypertonic then, water flows out by exosmosis.

Here's an image which would surely give a clear idea about tonicity:
