- Eukaryotes are organisms that contain more than one cell with membrane-bound organelles and a nucleus.

- Organisms that contain only one cell and do not contain a nucleus or membrane-bound organelles are known as prokaryotes.

Explanation:

According to their structural and functional complexity, organisms can be classified into eukaryotes and prokaryotes.

Eukaryotic organisms are formed by cells that have a true nucleus -where DNA is located- and specialized structures called organelles, with a system of endomembranes that compartmentalize the intracellular space. These organisms are usually pluricellular, given the ability of eukaryotic cells to group together to form tissues. Prokaryotic organisms are single cells, lacking a nucleus - genetic material is scattered in the cytoplasm - and do not possess organelles.  The prokaryotic cells that form these organisms are incapable of binding together, so they do not form tissues.

Some unicellular organisms are prokaryotic cells, like some parasitic microorganisms, such as amoebas.
