Egg Lab Day 3

No Daily Questions today - I had you jot down a couple slides that help show what did and didn't happen so far with our Eggs:

 Now to our EGGS!!!

We took them out of the corn syrup and observed that they were VERY "deflated" and flimsy.  We discussed this was because the water that had diffused INTO the egg yesterday diffused back OUT of the egg in order to maintain a constant water balance inside and outside of the cell.  The Corn Syrup (a very concentrated Sugar solution) could NOT pass through the membrane.  In OUR cells sugars move through specific transport proteins.  These are not present in the eggs membrane.



As you can see it is VERY flimsy and deflated because
water moved from inside the egg back out.

We know this because there is much more solution left in the beaker than we put in yesterday:

Yesterday we added 75mL of Corn Syrup.  Today there was approximately 100mL of solution

After making our observations we placed our eggs into 100ml of water and just for fun I let you add food coloring to see what happens!!!

Here is What happened at a molecular level today!
