Hey Guys,
We just did our first Sac today on cellular processes in relation to osmosis in an chicken egg plasma membrane.
- the egg shells were removed by the teachers with vinegar.
- we had 4 eggs and 4 different substances;
1. distilled water (egg increased in weight)
2. 1M salt
3. 5M salt
4. 5M Starch
- we placed each egg in the beaker with solution and recorded their weight ever 10 minutes for 60minutes.
- we found that some eggs became large obvious due to being put in a hypotonic solution.
- we found that some eggs became smaller obvious due to being put in a hypertonic solution.
What is the effect of the varying solution upon the egg specifically? i.e what will the 5M of starch do to the egg?
Thanks
PS. what does the vinegar specifically do to the plasma membrane
