From the paper "Regulation of Water and Solute Balance in Cells" it is clear that the dialysis tubing only allows a selected kind of substances, which are smaller in molecular size, to readily pass through micro-pores of its membrane, i.e. it has a selective permeability to molecules. ... Living cells require nutrients from their surrounding and at the same time, get rid of waste products in their environment. This exchange of substances between the internal and external of a cell is very important...

The paper "Studying the Impact of Solute Concentration on the Rate of Osmosis" discusses that Osmosis is defined as the movement of water molecules through a selective membrane (Freeman, 2010). Osmosis occurs so as to balance the water potential on either side of the membrane. ... It is essential to state that water potential is used to describe the tendency with which water moves from one region to another. This experiment was carried out in order to determine how the rate of osmosis changes under...

A solid that dissolves in a solvent is a Solute.... Solvent of a given mass dissolves a fixed amount of a given Solute at a particular temperature.... The fixed amount of Solute forms a saturated solution at that particular temperature.... When temperature increases more Solute dissolves because of the increase in molecular energy of water molecules that increases the interaction of water and Solute particle (Giulietti, 1996) However, the amount of solution does not either increase or decrease the rate of crystallization....
