Membrane-bound organelles
B
Presence of peptidoglycan in cell walls
C
Ability to perform photosynthesis
D
Linear DNA
Verified step by step guidance1
Understand the characteristics of the domain Bacteria. Bacteria are prokaryotic organisms, meaning they do not have membrane-bound organelles.
Recognize that bacteria have a unique component in their cell walls called peptidoglycan, which is a distinguishing feature of this domain.
Consider the ability to perform photosynthesis. While some bacteria can perform photosynthesis, it is not a universal characteristic of all bacteria.
Examine the structure of bacterial DNA. Bacteria typically have circular DNA, not linear DNA, which is more common in eukaryotic organisms.
Conclude that the presence of peptidoglycan in cell walls is a defining characteristic of the domain Bacteria, distinguishing them from other domains.
