around and it was 60.6 grams. This is definitely a huge difference from when the egg started out. Next when our egg was undergoing the hypotonic solution it's circumference was 20 cm. around and it was 90.8 grams. Now looking at our hypothesis and comparing it to our data, we can say that our data does support our hypothesis.
6. Osmosis is the diffusion of water, it takes water from a high concentration to a low concentration and it doesn't require energy at all. It is a form of passive transport. Water is being moved in and out of the egg. The substances will move to the area of low concentration and this will make the egg hypotonic.
7. Passive transport is when you are going from an area of high concentration to an area of low concentration, while active transport is going from low concentration to high concentration. Also active transport requires energy (ATP) to work while passive transport take no energy (ATP) to work. Also passive transport just goes with the flow of the concentration gradient while active transport goes against the flow of the concentration gradient.
8. Some errors that we had were that we dropped the egg on the table and it exploded everywhere.

The transport of water and other types of molecules across membranes is the key to many processes in living organisms. Many of these transport processes proceed by through membranes which are selectively permeable, allowing small molecules to pass but blocking larger ones. These processes, including and dialysis, are sometimes called passive transport since they do not require any active role for the membrane. Other types of transport, called , involve properties of a to selectively "pump" certain types of molecules across the membrane.
In today’s experiments we will explore membrane transport processes, focusing on passive transport, specifically diffusion of molecules through various types of matter and across semipermeable membranes
