How do you know? 4- How do nerve cells, Elodea leaf cells, and spirostomum compare in size? 5- Even before examining eukaryotic versus prokaryotic cell structure, would you predict that the mammalian nerve cells, Elodea leaf cells, and the protozoan Spirostomum are eukaryotic or prokaryotic cells? Why? LAB 4-B 1- Which cells are the smallest-bacteria. Elodea or ... click for more
