The Effect Of Sucrose Solutions On Osmosis

Osmosis and diffusion are both types of transports. Diffusion is the process of which molecules spread from areas of high concentration, to areas of low concentration. Osmosis is the diffusion of water through a membrane, moving molecules from an area of high concentration, to an area of low concentration. The capability of an extracellular solution to move into or out of the cell is known as tonicity. Three terms are used when relating to tonicity; Hypertonic, Hypotonic, and Isotonic (khan, 2016). In hypertonic environments (where there are more solutes outside than inside the cell) cells will lose water. In hypotonic environments (where there are less solutes outside than inside the cell) the cell will gain water. When solute concentration is even both in and outside of the cell there is no water movement so the cell would be in an isotonic environment (Figure 1).

Purpose

The purpose of this experiment was to find the effect of sucrose solutions on osmosis.

Methods

In the beginning of the experiment, all groups were instructed to write their group members initials and hour on the 250 ml beaker given to us. Next we poured 75ml of our tables designated sucrose solution into our beaker. There were 4 sucrose solutions: 0 percent, 5 percent, 10 percent, and 15 percent. After pouring in our solution we used a potato cork to cut out 4 cylinder pieces of potato cores, then sliced them until they were 2.00 cm even in length and weighed and recorded the mass of all 4
