Question

The picture shows an experimental set up for the process of osmosis. The potato has a cavity on top, as shown in the picture. Some sugar solution is poured into the cavity and the potato is placed in a beaker of water. After some time, it is observed that there is a rise in the level of liquid in the cavity. This confirms that

Answer 1

Answer;

A) Water from the beaker has moved into the cavity.

Explanation;

• Osmosis is a physiological process which involves the movement of water molecules from a region where there are highly concentrated to a region where they are lowly concentrated through a semipermeable membrane.
• In the experiment water molecules moved from the beaker where they are highly concentrated to the cavity where they are lowly concentrated. Sugar solution is a hypertonic solution while the water in the beaker is hypotonic therefore water moves osmotically from the beaker through the potato to the cavity.

Answer 2

The correct answer would be 

A) Water from the beaker has moved into the cavity.
