The Cucumber Extracellular Solution

This the Hypotonic and it has no salt with 50 mL of water. The mass is 12.9 grams.
( 0% of salt solution)

This the Hypertonic and it has 5 salt with 50 mL of water. The mass is 10.3 grams.
( 10% of salt solution)

This the Isotonic and it has 1.5 salt with 50 mL of water. The mass is 9.5 grams.
( 3% of salt solution)


The Final Results

This Data Table show that some of the water went in the cucumber rather than coming out. The Isotonic almost had the same mass but it was a .7 grams difference. The Hypotonic had a .5 increase in the mass and the Hypertonic had a .4 increase in the mass also. All the results seem accurate, basically showing that we did it correctly. The Extracellular solution had some affect in the cucumber like the texture and structure making it feel soft or hard.
Analyze Question
- We made the Hypotonic correctly because we added 0 grams of salt and 50 mL of water. The cucumber mass started from 12.9 grams to 13.4 grams. The reason to show that we did it correct is because some the water went in, which is why is has a .5 grams increase in the mass.
- We made the Hypertonic correctly because we added 5 grams of salt and 50 mL of water. The cucumber mass started from 10.3 grams to 10.7 grams, which is .4 gram increase, showing that barely of the water went out, but a bit of the water came in.
- The Isotonic was made correctly because the cell mass was 9.5 grams but was now 10.2. We add 1.5 grams and 50 mL of water. We had a close match to the mass, which was .7 grams. So some of the water came in than out the of the cucumber.
