QUESTION 1: Cells are generally microscopic, ranging in size from about 50 microns for animal cells to as small as 1 micron for bacterial cells. Why do you think that cells - animal, plant, or bacteria - don't get any bigger than this? Why do you think we are made of 75 trillion very small cells, rather than just a bunch of very large cells?

QUESTION 2: How do you think cells become specialized for their function? For instance, we all started our life as one single fertilized egg cell, but within weeks or months of conception, we had liver cells, heart cell, brain cells, muscle cells. How does one cell give rise to many cells with many different functions??

QUESTION 3: In what cells of your body would you expect to find a lot of mitochondria? Why?

QUESTION 4: Totally Optional: Please provide any commemts about the class - likes, dislikes, suggestions, glowing praise (just kidding).
