Osmosis lab

Today in lab we looked at osmosis, which is the movement of water across a semipermeable membrane from a region of low solute to a region of high solute.

We had two test tubes for the celery strips and two for the potato strips; one with salt water and one with distilled water.
We placed the potato and celery strips into the 4 test tubes and waited for 30 minutes. After we removed the strips from the test tubes the results were as listed below:

Saltwater potato was hypertonic- soft
Distilled potato was hypotonic- hard

Saltwater celery was hypotonic- soft
Distilled celery was hypertonic- hard
