How are organisms in the domain of eukarya different from those in the domain archaea?

Answer 1

Domain Archaea is made of the oldest known organisms, most use chemiosynthesis (inorganic elements) to make energy and are found in more hostile environments (extremeophiles) and are build on the cellular level to survive in them and are similar to Domain Prokaryota.

Domain Prokaryota organisms have no membrane bound organelles (chloroplasts, mitochondria, nucleus, ect.), their only genetic code is made of RNA and plasmids, they have a cell wall, are single celled, and move by cillia and flagella.

Domain Eucaryota are the most complex and diverse of the three domains. They have DNA as their primary genetic code, membrane bound organelles, and are equipped with a wide array of organelles for specific tissue and organ functions, but some function as single celled organisms.

Answer 2

Organisms in the domain Eukarya have membrane-bound organelles and a nucleus, while organisms in the domain Archaea lack membrane-bound organelles and have a simpler cell structure. Eukaryotic organisms also have linear chromosomes, while archaeal organisms generally have circular chromosomes.

Answer 3

The key difference that distinguishes living things of the domain Eukarya from other domains is that the cells of Eukarya have a nucleus. The other two domains are Bacteria and Archaea.

Answer 4

eukaryotes have organelles in membranes.
