Often, prokaryotic cells exist as simple unicellular organisms, but in some species, prokaryotic cells can grow together in colonies or filaments. In addition, some species, such as Cynaobacteria or Myxobacteria, demonstrate intercellular communication, or might even produce specialized cells and structures. However, only eukaryotic cells form the bodies of multicellular organisms with complex internal specialization.

Hello and thank you for submitting your question to Brainmass.

Here are two suggestions that come to my mind as two possible hypotheses.

There are two main structural differences between prokaryotic and eucaryotic cells:

a. The prokaryote cell has no defined nucleus, where the eukaryotic cell has a well defined nucleus.

b. The eukaryote cell maintain a cytoskeleton while prokaryotic cells do not have a well defined cytoskeleton.

Thus the hypotheses are:

1. Multicellular organisms needs specialized types of cells. For this we need many ...
