Question

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: Fungi (eukaryotes) have cell walls, but so do some prokaryotes (e.g., bacteria). So, the presence of a cell wall is not a unique feature of eukaryotes.
• Option B: Bacteria are unicellular organisms.
• Option C: Eukarya domain is characterized by the presence of membrane - bound organelles, including the nucleus (with a nuclear membrane). Domain C has membrane - bound organelles (Yes) and this is a key feature of eukaryotes.
• Option D: Bacteria are prokaryotes and do not have membrane - bound organelles.

Answer:

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