Which are characteristics of eukaryotic organisms? Select three options. may be single-celled or multi-celled have cells that contain DNA within a nucleus have cells that contain DNA in the cytoplasm are always single-celled include plants and bacteria include animals and plants

may be single-celled or multi-celled

have cells that contain DNA within a nucleus

include animals and plants

These and more are characteristics that set apart eukaryotes from prokaryotes. Eukaryotic organisms do not necessarily have to be multicellular. An example is the cyanobacteria and amoeba that are composed of one cell but are categorized with other eukaryotes.

Explanation:

Example of prokaryotes is bacteria while eukaryotes are plants and animals

Their major differences are that eukaryotes' DNA is delimited inside a nuclear membrane while prokaryotic cells have no nuclear membrane.

Eukaryotic cells have organelles like mitochondria and chloroplasts while prokaryotic cells do not.

Prokaryotic cells are generally of smaller size than eukaryotic cell.
