This is my first blog in this series. This blog is primarily intended for my cell biology and microbiology students at The Master's College. My background is in cellular immunology/microbiology and I have been teaching at the undergraduate level for 20 years. However I am by no means an expert in this field....there is just too much to know and a lot of things yet to discover about these smallest pieces of life.
I intend on blogging at least once a week to share insights from our classroom lectures and discussions.

So what are cells and what is the advantage to having every living thing made of cells? How do we define what a cell is anyway? The traditional way to define them is to distinguish them from viruses. Viruses are typically smaller than cells and do not have a lot of things which cells have. Recently some very large viruses with membranes and cellular biochemistry have been discovered. One of these is the Mimi virus... a pretty big virus. It is bigger than some bacteria. It has metablic pathways to make amino acids and nucleotides. So is this is virus or a cell? http://www.microbiologybytes.com/virology/Mimivirus.html
Then there is the issue of unicellular life. I have a sneaky suspicion that unicellular life does not really exist. Curiosity peaked. Stay tuned.
Students please feel free to answer my questions with a reply.
