Question

question 19 the diagram below shows the structure of a bacterial cell. which of the following distinguishes this bacterial cell from eukaryotes? a dna in the bacterial cell is always in contact with the cytoplasm, and all eukaryotes have dna located inside a nucleus. b ribosomes are found in the cytoplasm of the bacterial cell, and eukaryotes do not have ribosomes. c the bacterial cell is a unicellular organism, and all eukaryotes are multicellular. d the bacterial cell has both a cell membrane and a cell wall, and eukaryotes have only cell membranes.

Explanation:

Bacterial cells (prokaryotes) lack a nucleus, so their DNA is in the cytoplasm. Eukaryotes have a membrane-bound nucleus containing DNA. Other options are incorrect: eukaryotes have ribosomes, some are unicellular, and some have cell walls.

Answer:

a. DNA in the bacterial cell is always in contact with the cytoplasm, and all eukaryotes have DNA located inside a nucleus.
