Which of the following clues would tell you if a cell is prokaryotic or eukaryotic?
a) whether or not the cell contains dna.
b) presence or absence of ribosomes.
c) whether or not the cell is partitioned by internal membranes.
d) the presence or absence of a rigid cell wall.
e) whether or not the cell carries out cellular metabolism.

The right answer is C.

The eukaryotic cells have a nucleus which is the most voluminous organelle and which is delimited by a double membrane called nuclear envelope. In the nucleus the replication and transcription of DNA is carried out; the translation is done in the cytoplasm of the cell.

Eukaryotes have cytoplasmic partitions allowing the formation of organelles (nucleus endoplasmic reticulum, golgi apparatus, lysosomes, peroxisomes and vesicles), these organelles swim in the cytosol which in eukaryotes is fluid with presence of flux thanks to the cytoskeleton (see more classes). The plasma membranes are not lined with a wall for animals, but doubled for plants (pectocellulosic wall) and for fungi (polysaccharide wall); in all cases there is absence of peptidoglycan but presence of sterols.

since there are no options posted i'll give you a few examples.
