Which of the following matches the organisms described with the correct domain? Which of the following matches the organisms described with the correct domain? bacteria--unicellular, eukaryotic organisms that always lack cell walls eukarya--single-celled and multicellular organisms, with a defined nucleus and a variety of nutritional sources bacteria--unicellular, eukaryotic organisms with cell walls that do not contain peptidoglycan archaea--multicellular, eukaryotic organisms that do not have cell walls

All living organisms have been classified into three general groups called DOMAIN. Domain Eukarya is one of the three domains, the other two being; bacteria and archaea. The distinguishing factor between members of Eukarya called eukaryotes and the other domains called prokaryotes is the possession of a membrane-bound enclosure which houses their genetic material (DNA) called NUCLEUS. Eukaryotes also has complex organnelles e.g mitochondria, Chloroplast, golgi complex etc. that are bounded by a membrane unlike prokaryotes that do not.

Asides possession of membrane-bound nucleus and organnelles, eukaryotes can either be single-celled (unicellular) e.g yeast or multicellular e.g plants, animals etc.
