Osmosis is defined as the movement of weewee molecules across a
part pervious membrane from a region of racy piddle concentration
to a region of low peeing concentration. In a towering concentration of
water supply the quantity of solute (e.g. sugar) is low. This could be called a
weak or dilute solution. In a low concentration of water the amount of
solute (e.g. sucrose) is high. This could be called a strong or
concentrated solution. When two much(prenominal) solutions are divided by a
partially porous membrane the water will move from the area of high
concentration to the area of low concentration, until both sides are
competent (have reached equilibrium).

Knowing that osmosis will occur across a partially permeable membrane
whenever there is a difference between the water concentrations on the
two sides of the membrane, and knowing that when this happens to carrels
they will both become turgid if water flows into them, or flaccid if
water flows out of them, and thus change their volume, we want to test
the speculation that:
If the concentration of a solution into which a piston chamber of stump spud is
located is greater than a certain level the cylinder will contract, and
if the concentration is less than that level it will expand. This undersurface
be seen in living cubicles.



The stall membrane in cells is partially
permeable and the vacuole contains a sugar/salt solution. So when a
cell is placed in distilled water (high water concentration) water
will move across the partially permeable membrane into the cell (lower
water concentration) by osmosis, making the cell swell. This cell is
now referred to as turgid. If done with potato cells the cells would
increase in volume and mass because of the extra water. If these
potato cells were placed in a solution with a low water concentration,
then the opposite would happen. Water would move out of the cell into
the solution. In extreme cases the cell membrane breaks away from the
cell wall and the cell...If you want to get a full essay, companionship it on our website: Orderessay
