There are many cells in a living body; in fact, the Cell Theory states these three things:
1. Cells are the basic units and functions of life
2. All living things are composed of cells
3. All cells are produced by other cells
I have really enjoyed this unit, and found it interesting to see that these cells have even tinier parts inside them!! I have always been interested in the medical field (I want to become a doctor when I grow up), so as we learn these small things, they really build up. I wouldn't say I had a famous part, because I honestly liked the whole unit, but if I had to choose, it would be when we looked up tiny things under microscopes...IT WAS SO COOL!!
