Essay / Research Paper Abstract
This 5 page report discusses and explains
the concept of osmosis which is how one element or
ingredient of a solution flows through a membrane while
other components of a solutuon are shut out and unable to
pass through the membrane. In order to determine which
membranes allow the flow of which constituents of a solution
requires experimentation since not all membranes act the
same way. Bibliography lists 8 sources.

Unformatted sample text from the term paper:
is how one element or ingredient of a solution flows through a membrane while other components of a solution are shut out and unable to pass through the membrane. In
order to determine which membranes allow the flow of which constituents of a solution requires experimentation since not all membranes act the same way. To put it in
even more simple terms, water is the solvent in which molecules and constituents such as salts are the solute particles. What happens when there is a high concentration solution on
one side of a membrane and a dilute on the other, the solutions tend to move toward equalizing, so what happens is that the solvent (water in this circumstance) moves
from the dilute side to the concentrated side thus diluting it (and concentrating the side it left) until both are equal. This result is then referred to as the osmotic
pressure. Why Do an Osmosis Lab Experiment? In general, non-scientists most often think of osmosis in connection with the natural chemical processes through which plants transport water within their
individual systems. Canny (1998) explains that the varying amounts of transported water in plants may be attributed to their different demands for water supply which may be performed by their
water-management system. He adds: "Evaporation from the leaves pulls water to the top of a tree, but living cells make that possible by protecting the stretched water and repairing it
when it breaks. Plants are thirsty creatures. ... For every kilogram of organic material made by a plant, 500 kilograms of water are absorbed by the roots and evaporated, or
transpired, from the leaves. Consequently, management of that stream of water dominates the life process of plants. The question is: How is that management achieved? In general terms, the answer
