Question

question 6 (1 point) the presence of which of the following would be used as evidence to determine whether a cell is prokaryotic or eukaryotic?
o a ribosomes
o b cell wall
o c mitochondria
o d dna

Explanation:

To determine if a cell is prokaryotic or eukaryotic, we analyze each option:

• Option a: Ribosomes are present in both prokaryotic and eukaryotic cells, so they can't distinguish the two.
• Option b: Some prokaryotes (like bacteria) and some eukaryotes (like plants, fungi) have cell walls, so cell walls aren't a definitive marker.
• Option c: Mitochondria are membrane - bound organelles. Prokaryotic cells lack membrane - bound organelles, while eukaryotic cells have them. So the presence of mitochondria indicates a eukaryotic cell.
• Option d: Both prokaryotic and eukaryotic cells have DNA (prokaryotes have circular DNA in the nucleoid, eukaryotes have linear DNA in the nucleus), so DNA presence doesn't distinguish them.

Answer:

c. mitochondria
