Egg Diffusion Lab Conclusion!

       In this lab we soaked an egg in deionized water and another egg in sugar water for 48 hours. Before leaving the fragile egg, my teammates and I took measurements of both eggs. We calculated the circumference and the mass. After waiting for the initial time, we analyzed our final observations and measured the circumference and mass again. Finally, everyone in the class shared their percent change of both solutions.
       Looking at the class data, the mass and circumference of the egg decreased due to the egg's hypertonic environment (sugar water). Taking a closer look inside the egg, the water inside leaves to go to a "high-low" concentration, though the solute outside can not enter due to being too big. This situation leads to the egg shriveling up since there is a smaller solvent inside.
       When the egg is being added to vinegar, later the shell of the egg will dissolve and the membrane becomes visible. This procedure needs to happen to complete thee lab in which now the possibilty of changing the cell  is attainable. Now when the egg is added to the solute, the egg will adapt and passive diffusion may occur throughout the egg.
       This lab demonstrates a biological principle which is the process of diffusion. Diffusion spreads particles in a faster manner throughout the cell membrane.
       When salting the roads, the plants will start to shrivel up due to being in a hypertonic environment. Though, when there are plants in grocery store, the fresh vegetables are sprinkled with water to keep a hypotonic environment for them which will make the plants more happy.
       Based on this experiment, I will use this information to test an egg in different conditions, and to test if the change is hypotonic or hypertonic. These tests will help my knowledge in ddiffusion, hypotonic, and hypertonic.
