2-4 Potato Lab

Front

What was the purpose of the 2-4 Potato Lab?

Back

The purpose of the lab was to see the effect of salt on a potato.

Front

In what solution did the potato gain mass?

Back

The potato gained mass in distilled water.

Front

What is osmosis?

Back

Osmosis is the movement of water across a membrane.

Front

If a cell containing 5% salt is placed into a glass of water with 20% salt, how is the water compared to the cell?

Back

The water is hypertonic compared to the cell.

Front

What happens to an animal cell placed in a hypertonic (salty) solution?

Back

The animal cell will shrink (get smaller).

Front

Define hypertonic solution.

Back

A hypertonic solution has a higher concentration of solutes compared to another solution.

Front

Define hypotonic solution.

Back

A hypotonic solution has a lower concentration of solutes compared to another solution.

Front

Define isotonic solution.

Back

An isotonic solution has the same concentration of solutes as another solution.

Front

What is the effect of salt on potato cells?

Back

Salt causes water to move out of potato cells, leading to shrinkage.

Front

What is the role of distilled water in the potato lab?

Back

Distilled water provides a hypotonic environment for the potato, allowing it to gain mass.
