Day 6-Cell Membranes

Today we began class by discussing cell membranes. We learned that all living organisms have cell membranes(except for viruses). They are semi-permeable based on the size of the molecule and if it is polar or non-polar. We learned that they are made up of proteins which are also known as "gate keepers" because they are where molecules cal pass through the membrane. We also learned that osmosis occurs through these proteins because they are hyper-philic or water loving. The rest of the class consisted of a short lab quiz and our first house case.
