Final answer:
The domain Eukarya is eukaryotic, while the domains Archaea and Bacteria are prokaryotic. Eukaryotic cells have a membrane-bound nucleus and organelles, unlike prokaryotic cells.
Step-by-step explanation:
The domain that is eukaryotic with nuclei and membrane-bound organelles is known as Eukarya. Organisms in this domain, such as plants, animals, fungi, and protists, have cells with a membrane-bound nucleus and various organelles like mitochondria, chloroplasts, and endoplasmic reticulum,
which are specialized for certain functions within the cell. In contrast, the domains Archaea and Bacteria consist of prokaryotic organisms. These organisms do not have a nucleus or membrane-bound organelles. Their cells are generally smaller and less complex, with a single, circular piece of DNA floating freely in the cell. Archaea and Bacteria are distinct from each other based on membrane structure and ribosomal RNA (rRNA), despite both being prokaryotic.
