Background:
The cell membrane surrounds all cells and controls what comes in and what goes out of the cell. It is selectively permeable (it permits certain things to enter and prevents other things from coming in). There is a phospholipid bilayer in which the hydrophobic tails point inward and the hydrophilic heads point outwards. Inside this plasma membrane there is usually an integral protein, cholesterols, a protein channel (for substances that can’t enter through the phospholipid bilayer), a peripheral protein, and a transport protein to pump molecules.
There are six main types of cellular transport: osmosis, diffusion, facilitated diffusion, active transport, endocytosis, and exocytosis. Osmosis is the movement of water across a selectively …show more content…
The hypothesis for egg one (vinegar) stated: If the effect of vinegar on egg mass due to osmosis is tested, then the egg will gain mass. This was proven because the mass of egg one increased after being placed in vinegar for 48 hours. The egg weighed 100.3 grams after being placed for the first time in vinegar. After it was placed in fresh vinegar for 48 hours, the mass increased to 102.6 grams. The hypothesis for egg two (water) stated: If the effect of water on egg mass due to osmosis is tested, then the egg will gain mass. This was proven because the mass of egg two increased after being placed in water for 48 hours. The egg had a mass of 97.3 grams after being placed in vinegar for six days. The mass increased to 101.1 grams after it was placed in water for 48 hours. The hypothesis for egg three (corn syrup) stated: If the effect of corn syrup on egg mass is tested, then the egg will lose mass. This was proven because after 48 hours in corn syrup, the egg lost mass. The egg weighed 97.3 grams after being placed in vinegar for 6 days. The mass decreased to 86.7 grams after being placed in corn syrup solution for 48 hours. The masses of the eggs changed due to the process of osmosis. The masses of egg one and two increased because they were placed in hypotonic solutions, whereas, egg three was placed in a hypertonic
