Question

Question 1

Question 2

The water level outside of the potato has decreased because the water evaporated.

Question 3

Which of the following solutions is considered hypotonic? (Points : 3)

Question 4

A good purpose statement for this lab is: The purpose of this lab experiment is to show that water molecules move from high to low concentration; the water will move by osmosis. (Points : 2)

Question 5

It is not necessary to take measurements of the water in the potato in this lab, you can see if there is a change (osmosis) just by looking at it. But you would want to collect data for the results in a written lab report.

Question 6

The graph or chart (results) with the information for this lab should include: beginning and ending data, labels, units and times of measurement if written in a formal lab report.

Question 7

The conclusion is usually the longest section of a lab report. This is the section where you explain or analyze the results you found.

Question 8

Question 9

The cell membrane around the potato cells is permeable to water molecules. This explains why the salt does not move into and out of the cells but the water molecules do........... raising (increasing) the water level.

Question 10

Evidence to support osmosis in this lab might include the water level rising inside of the potato filled with salt water.

Question 11

In your osmosis/potato lab, the molecules of salt are the solute.

Question 13.

In your osmosis/potato lab the mixture of the salt and water is the solution.
