Egg Diffusion Lab

     I this lab, we learned about diffusion. And we demonstrated this on eggs. We put eggs in vinegar than de-ionized water than sugar water. 

     When we put the egg in de-ionized water, it grew exponentiation. This happened because of passive diffusion. The process where molecules pass through the membrane without any energy usage and the cell can not control it. The egg grew because it was absorbing water for the outside solution which had a higher concentration than the the cell which had a lower concentration. This is known as hypertonic.

     A cells environment changes because it wants to achieve equilibrium. This happen through the process called diffusion which is explained above. This is shown by the contents of the cell as well as the size of it. Adding vinegar it dissolved the eggs cell, then putting it in de-ionized water made the egg grew, that lastly we put it in a sugary solution which made it shrink.

     This lab shown the biological principal know as diffusion and equilibrium because we saw the affects of these principals on the eggs.

     I can apply this to life when you drink water from the ocean. The ocean water is extremely salty so the amount of water is unbalanced. So the water leaves the cell through diffusion and leaves the salt making you more thirsty.

     After this experiment, I would like to test the effects of salt. For example, putting salt on raw meat and explain why meat does not rot or mold as fast.
     Markets put water on vegetables of fruits to keep the food wet and not dry out.
