Question

prokaryotes and eukaryotes are primarily distinguished by the absence or presence of internal, membrane - bound organelles. are prokaryotic cells at an evolutionary disadvantage because they lack organelles?
no; eukaryotic organelles are expelled each time the cell divides.
no; although prokaryotic cells are comparatively less efficient than eukaryotic cells, they are still able to carry out the processes necessary for survival and reproduction.
yes; without organelles, prokaryotic cells cannot photosynthesize or respire.
yes; without organelles, prokaryotes are unable to bring together the reactants needed for biological reactions.

Explanation:

Prokaryotic cells lack membrane - bound organelles but can still perform essential life - sustaining processes like metabolism and reproduction, which means they are not at an evolutionary disadvantage. Eukaryotic organelles are not expelled during cell division. Prokaryotes can photosynthesize (e.g., cyanobacteria) and respire, and can also organize reactants for biological reactions.

Answer:

No; although prokaryotic cells are comparatively less efficient than eukaryotic cells, they are still able to carry out the processes necessary for survival and reproduction.
