The diagram below shows the structure of a bacterial cell. Which of the following distinguishes this bacterial cell from eukaryotes? DNA in the bacterial cell is always in contact with the cytoplasm , and all eukaryotes have DNA located inside a nucleu The bacterial cell is a unicellular organism , and all eukaryotes are multicellular Ribosomes are found in the cytoplasm of the bacterial cell, and eukaryotes do not have ribosomes The bacterial cell has both a cell membrane and a cell wall, and eukaryotes have only cell membranes

Answer 1

The statement that best distinguishes bacterial cells from eukaryotic cells is: DNA in the bacterial cell is always in contact with the cytoplasm, and all eukaryotes have DNA located inside a nucleus.

This is because bacterial cells are prokaryotic, meaning they do not have a defined nucleus; instead, their DNA is located in the nucleoid region, which is not separated from the cytoplasm. In contrast, eukaryotic cells have a true nucleus that encases their DNA.

The other statements are incorrect or too broad:

• Not all eukaryotes are multicellular; there are unicellular eukaryotes (e.g., yeast, protozoa).
• Eukaryotes do have ribosomes; they are just structurally different from those found in bacteria.
• Eukaryotes can have cell walls (e.g., plants and fungi) in addition to cell membranes, while bacterial cells have both a cell membrane and a cell wall.
