Prokaryotes and eukaryotes are distinguished mainly by whether internal membrane-bound organelles are present. Are prokaryotes at an evolutionary disadvantage because they do not have organelles?
A) Yes. Without organelles, prokaryotic cells cannot photosynthesize or respire.
B) Yes. Without organelles prokaryotes are unable to bring together the reactants needed for biological reactions.
C) No. Prokaryotic cells are less efficient than eukaryotic cells, but they are still able to carry out the processes necessary to sustain life and reproduction.
D) No. Eukaryotic organelles are expelled each time the cell divides.
