Shell Less Egg Lab Report

Problem question:
When a Shell - less egg is placed into a beaker of corn syrup, will there be any water going into or out of the egg and if the shell - less egg is placed in a beaker of distilled water will be any net flow of water going into or out of the egg.

Hypothesis:
If a shell - less egg is placed into a beaker of corn syrup solution, then there will be a net flow of water going into the egg because the water molecules will be small enough to pass through the membrane of the egg.

If a shell - less egg is placed into a beaker of distilled water, then there will be a net flow of water going out of the egg because since the egg and the solution outside of it need to reach equilibrium the molecules inside egg will need to come out.
Materials:

(2) raw eggs (pre-soaked in vinegar)
(2) clear plastic cups
(2) 150 mL beakers
Distilled water
Corn syrup solution permanent marker
Paper towels
Electronic balance

Procedure (Day 1): get your eggs.
Find the mass of each egg, record the masses see what the vinegar did to the uncooked eggs, write your observations put one of the eggs into a cup.
Pour corn syrup into the cup to cover the egg. Using a marker, label the cup "syrup" and add your period # and initials. place a 150 mL beaker on top of the egg put the second egg into the last cup.
Pour enough water into the cup to cover the egg. Using a marker, label the cup "water" and add your period # and initials.
Put a 150 mL beaker on top of the egg.
Clean up your area
Day 2: remove the eggs from the cups and dry the eggs with a paper towel.
Find the masses of the eggs, record the masses look at what happened to your eggs and write your observations.
place the eggs back into their solutions.
Clean up
Day 3: remove the eggs from the cups and pat the eggs dry with the paper towel.
Find the masses of the eggs, record the masses observe what happened to the eggs and write your observations.
Give the eggs to the teacher.
Pour the solutions into the drain and throw away the cups
Clean up.

Data/Observations:

Pre - Lab questions:
What is the cell (plasma) membrane made of?
The Plasma membrane is made of a semi-permeable bilayer of phospholipids embedded with proteins.
What are two jobs of the membrane?
On of the job plasma membrane is to act as a molecular gatekeeper to prevent certain substances from crossing, while granting access to others.
What can easily pass through the membrane?
Simple elements and compounds, like water.
What types of substances need carrier proteins to cross the membrane?
Larger and more complex carbohydrates need carrier proteins to pass through the membrane.
Define diffusion. Diffusion is the movement of molecules down a concentration gradient from an area of higher concentration to an area of lower
concentration.

Define osmosis. the movement of water molecules across a membrane from an area of higher concentration to an area of lower concentration
7. How are diffusion and osmosis similar?
They both have to do with the movement of molecules.
Explain the concept of a hypertonic solution. A hypertonic solution is a situation where a cell has a greater concentration of dissolved materials or water on the outside and less inside.
Explain the concept of a hypotonic solution.
A hypotonic solution is a situation where a cell has a greater concentration of dissolved materials on the inside of the cell, this can lead the cell to burst from the pressure.
What does it mean to be isotonic?
An Isotonic solution is when the outside and the inside of the cell has the same osmotic pressure.
