BIOLOGY QUESTION!!!!!!!!!!!!!!!!!!!!!!…

This is because of the properties of osmosis. If the membrane is only semi permeable (only some things can go through) ... and water can p where the solutes can not, a water potential is created... this causes the water to move in the direction that will make the concentrations the same on each side of the membrane... ex: by rushing out of the cell when the concentration outside is higher than inside, the water dilutes the concentration outside creating an equilibrium ... one thing that can make osmosis confusing is the fact that its pretty easy to remember that solutes move down their concentration gradient, however with osmosis it seems to be the opposite. the water moves against the solutes concentration gradient, to the higher concentration... a good way to remember this is to keep in mind that the water is moving down IT'S concentration gradient (to the side with more solutes, but LESS water) ... hope this answers it for you... I'm attaching a link just in case :)
