Answer:
have similar cell structures
Step-by-step explanation:
Archaea and bacteria are single-cell organisms that are classified as prokaryotes. They both possess similar cell structures as they tend to both have the same shape and size when viewed with a microscope. They both do not have a nucleus or other membrane-bound organelles like mitochondria and chloroplasts. One of the structures they share in common is the thread-like structure called flagella, which they use as in navigation around their environment.
Irrespective of the fact that they have similar cell structure, advanced studies have shown that archaea and bacteria have different genetic coding made of different proteins. Both cells also differ in the composition of their cell walls.
