Procaryotes are distinguished from eukaryotes on the basis of what structure? (more than one answer is correct)
a. a membrane-bound nucleus
b. plasmid dna
c. rna molecules
d. presence of mitochondria or chloroplasts

a. a membrane-bound nucleus

d. presence of mitochondria or chloroplasts

Explanation:

Procaryotes are the organisms that lack membrane-bound well-defined nucleus in their cells. These organisms have their DNA present in the cytoplasm itself. Procaryotes also lack the membrane-bound organelles such as mitochondria, chloroplasts, Golgi apparatus, etc.

On the other hand, eucaryotes have a membrane-bound well-defined nucleus in their cells to house DNA in it. These organisms also have membrane-bound organelles in their cells. Examples of procaryotes are bacteria and archaea while animals and plants are eucaryotes.
