Question

comparing types of cells
students are comparing two organisms in the table below.

organism 1	organism 2
has complex structure	single - celled
multi - cellular	no nucleus
has a membrane - bound nucleus	has ribosomes

part a
one student concludes that organism 1 must be eukaryotic because it has ribosomes. which statement about this conclusion is true?
a the student is completely correct because only eukaryotic organisms have cells with ribosomes
b the student is completely incorrect because only prokaryotic organisms have cells with ribosomes
c the student is correct that it is eukaryotic, but incorrect about only eukaryotes having ribosomes
d the student is incorrect that it is eukaryotic, but correct about only eukaryotes having ribosomes
part b
which two statements support the answer to part a?

Explanation:

Ribosomes are present in both prokaryotic and eukaryotic cells. Organism 1 is eukaryotic as it has a membrane - bound nucleus. So the student is correct that Organism 1 is eukaryotic but wrong about ribosomes being exclusive to eukaryotes.

Answer:

C. The student is correct that it is eukaryotic, but incorrect about only eukaryotes having ribosomes
