Question

which three of the following characteristics distinguish bacteria from archaea?

☐ inclusions present in the cytoplasm
☐ presence of peptidoglycan in cell walls
☐ type of lipid molecules found in plasma membranes
☐ motility structures are present
☐ chromosome is double - stranded dna
☐ capsules and slime layers found on most cells
☐ 70s ribosomes present in cytoplasm

Explanation:

1. Presence of peptidoglycan in cell walls: Bacteria have peptidoglycan in their cell walls, while archaea do not. This is a key distinguishing feature.
2. Type of lipid molecules found in plasma membranes: Bacteria have ester - linked lipids in their plasma membranes, and archaea have ether - linked lipids. This difference in lipid types is a distinguishing characteristic.
3. Capsules and slime layers found on most cells: Capsules and slime layers are more commonly found on bacterial cells compared to archaeal cells.

Answer:

• presence of peptidoglycan in cell walls
• type of lipid molecules found in plasma membranes
• capsules and slime layers found on most cells
