Detailed Differences Between Eukaryotic and Prokaryotic Cells
DETAILED DIFFERENCES BETWEEN EUKARYOTIC AND PROKARYOTIC CELLS Cells are divided into two categories namely the Prokaryotes and Eukaryotes. These two have varying differences between them. Speaking in simple cell biology words, prokaryotes are primitive, simple organisms that lack membranous cell organelles. The opposite of this are eukaryotes, which are advanced and complex organisms having membrane bound cell organelles. Seemingly simple in structure and markedly different from eukaryote and protist organisms, prokaryotic cells are believed to
