To wrap up the tour, let's use a couple of more "tangible" comparisons to make all of this clear: If a _protein_ were of the size of a _grain of rice_, then a cell will be the size of a room 10 m x 10 m x 10 m. (approximately 33 ft x 33 ft x 33 ft for the non-metric minds) And, if a _cell_ were the size of a _grain of rice_, then the _tip of your pinkie finger_ will be the size of that 10 m x 10 m x 10 m room. Bottom line: "Plenty of proteins in them cells, and plenty of cells in them pinkies"
