Prokaryotic cells are smaller than eukaryotic cells. What advantages might this give the prokaryote? Why? What advantages might a large cell size provide eukaryotes? Why?

Prokaryotic cells are smaller to facilitate the diffusion of ions and organic molecules that enter them to other cells. Thus, smaller cells do not need organelles and thus do not need to spend energy to obtain substances through the membranes of the organelles. However, larger cells need organelles to separate cellular processes, which allows the construction of more complex molecules.
