Question

the chart shows the characteristics of organisms that are found in three domains
based on the information in the chart, which statement best describes domain c?
a. domain c represents the eukarya domain because only eukaryotic cells have cell walls.
b. domain c represents the bacteria domain because bacterial cells are always multi - cellular
c. domain c represents the eukarya domain because eukaryotic cells contain nuclear membranes.
d. domain c represents the bacteria domain because bacterial cells contain membrane - bound organelles.

Explanation:

• Option A: Incorrect. Not only eukaryotic cells have cell walls (e.g., some prokaryotes like bacteria have cell walls).
• Option B: Incorrect. Bacterial cells are single - celled.
• Option C: Correct. Eukarya domain has nuclear membrane, membrane - bound organelles (as in Domain C characteristics: nuclear membrane - Yes, membrane - bound organelles - Yes).
• Option D: Incorrect. Bacterial cells (prokaryotes) do not have membrane - bound organelles.

Answer:

C. Domain C represents the Eukarya domain because eukaryotic cells contain nuclear membranes.
