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:

• Domain A: Some single - celled, no cell wall, no nuclear membrane, has ribosomes, no membrane - bound organelles. This is characteristic of Archaea.
• Domain B: Single - celled, has cell wall, no nuclear membrane, no ribosomes (this is incorrect as all cells have ribosomes, but assuming chart data is to be followed), no membrane - bound organelles. This is not a typical domain description (but if we consider the data), but bacteria are single - celled prokaryotes.
• Domain C: Multi - cellular (no single - celled), has cell wall (fungi, plants which are eukaryotes have cell walls), has nuclear membrane (a key feature of eukaryotes), has ribosomes, has membrane - bound organelles. Eukarya domain (which includes plants, animals, fungi, protists) has nuclear membranes.
• Option A: False. Not only eukaryotic cells have cell walls (bacteria also have cell walls in some cases).
• Option B: False. Bacterial cells are single - celled.
• Option C: True. Eukaryotic cells (Eukarya domain) have nuclear membranes.
• Option D: False. Bacterial cells (prokaryotes) do not have membrane - bound organelles.

Answer:

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