Prokaryotic and eukaryotic cells

Prokaryotic and eukaryotic cells share many similar features, developed and fine-tuned through years of evolution. Interestingly, the majority of prokaryotic cells exist as simple unicellular organisms, and only on rare occasions can grow together in colonies or demonstrate any type of intercellular communication. Eukaryotic cells, however, form the bodies of multicellular organisms and regularly produce specialized cells and structures.

Identify and describe one or two structural and functional differences between prokaryotic and eukaryotic cells that you believe contribute to the ability of eukaryotic cells to form the specialized cells and structures found in multicellular organisms. While there are several differences between prokaryotic and eukaryotic cells, please limit your answer to those structural and functional differences that will assist in the evolution of multicellularity.
