What effect do structural differences have betweeen prokaryots and eukaryots
Dennis_Churaev [7]

Answer:

Prokaryotes are therefore able to lack membrane-bound organelles and have less complex internal structure. Eukaryotes are generally larger than prokaryotes, and have a less favorable surface-area to Page 5 volume ratio. This makes transport more complicated, requiring them to contain a larger variety of organelles.

The major structural advantage of eukaryotes over prokaryotes is the ability to form advanced, multicellular organisms. While eukaryotes can survive as both single-cell and multicellular organisms, prokaryotes don't have the ability to form complex structures or organisms.

What differences in structures are there between a prokaryotic and eukaryotic cell?

Comparing prokaryotes and eukaryotes

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
