The definition of diffusion is the movement of molecules from a high concentration to one of a low concentration. The cell membrane is a barrier that will allow water through it but not larger molecules like sugar or salt. So when you add these materials to the water you are causing the concentration of water to decrease in comparison to the concentration of water on the other side of the membrane without the sugar. So according to the physical laws water will move from a high concentration across the membrane into the the area of lower concentration trying to equalize it.

An equilibrium means that opposing processes are occuring in opposite directions at the same rate. When you dissolve something on one side then the water is hitting the membrane less often. This causes a net result of water coming from the other side.

Osmosis.
Osmosis is the movement of water; and it always moves from high density to low density. I.E; if there is more water INSIDE the cell than outside it, the water tends to move OUTSIDE, to equal it out.[HYPERTONIC SOLUTION] Likewise, when there is more water outside the cell than inside, the water moves from outside to inside. [HYPOTONIC SOLUTION]When the amount of water on both sides of the cell are equal, however, the water dosen't need to move. [that is called "equilibrium" or ISOTONIC SOLUTION].
So, in answer to your question, when there are more dissolved particles on one side of the membrane, they likely take the place of water molecules, resulting in one side of the membrane having less water than the other. therefore, the water will diffuse, in an effort to even out the water concentrations.
Hope this helps!

its called osmosis, the solid particles are not capable of passing thru the cell membrane walls which is why this is used to filter chemicals from the liquids that carry and sstore them in suspension, and a great way to purify solutions.

a million. Diffusion refers to passive circulate of a substance from a region of more advantageous concentration to diminish, increasing entropy of the equipment. Osmosis refers to passive circulate of water via a semi-permeable membrane. 2. concentration of solutes. Water will flow in the route of the better concentration of solutes. 3. I placed a drop of methylene blue into my aquarium. in a little while, the methylene blue had dispersed frivolously in the course of the aquarium, in spite of if there have been no major currents in there. Hypotonic: part of, or answer of, decrease concentration of solute than what you're evaluating it to. Hypertonic: part of, or answer of, more advantageous concentration of solute than what you're evaluating it to. Isotonic: part of, or answer of, equivalent concentration of solute to what you're evaluating it to. > Why is it risky to drink salt water ? it really is hypertonic compared on your cells. Water will pass out of your cells and also you'll develop into dehydrated. > Why do diabetics develop into thirsty ? We do? it truly is information to me! Your instructor likely needs you to assert that diabetics have a more advantageous concentration of sugar in the blood, and for this reason the blood can develop into hypertonic to the cells, dehydrating them. The homeostasis sensory equipment in the body senses that the cells are dehydrating, and the mind receives a "thirsty" signal. > what's the enormous difference between a solute and a answer ? Solute: stuff it truly is to be dissolved in a solvent. answer: homogeneous blend of solute and solvent. > what's the enormous difference between passive and lively delivery Use of ability. Passive delivery does no longer require the expenditure of ability. lively delivery calls for the expenditure of ability.

to reach homeostasis.
by dissolving particles on one side you've created high and low concentrations...you have to equal it out.
