CELLS!!!!

How can something so small have a big job to full fill? I think is awesome! You can never underestimate something so small. A cell is the basic structural and functional unit of all living things. The cell theory states that all organisms are composed of cells, and that the cells only come from preexisting cells. There are two types of cells, the prokaryotic  cells and the eukaryotic cells. Cells are the main line to every living thing. If there were no cells we would not exist at all.
