 Eukaryotes
Protists (mostly microbial eukaryotes) have membrane-bounded organelles not found in most other eukaryotes - such as contractile vacuoles and extrusomes.
Eukaryotes visibly influence the nature of our world.
Our concepts of beauty, logic and spirit are arguably derived from our observations of the eukaryotes.

And eukaryotic flagella and cilia have a core structure of nine pairs of microtubules around a central pair.
Dynein also functions here to achieve the types of movement necessary for these structures.
Ribosomes have been discussed several times already; they are found in both prokaryotes and eukaryotes and even in mitochondria and chloroplasts.

 Ask A Scientist - Eukaryote vacuoles in plants and animals
The predominant view is that eukaryotic organelles were independent prokaryotic organisms at some point in the distant past.
Why does a plant eukaryote have a large vacuole and chloroplast and an animal eukaryote does not?
(Eukaryotic cells have a distinct, membrane-bound nucleus; the more primitive prokaryotic cells, such as bacteria and blue-green algae, do not.) Plant cells are thought to have incorporated blue-green bacteria, which eventually became chloroplasts.

In the five-kingdom system of classification taxonomy, the study of the relationships of organisms, which includes collection, preservation, and study of specimens, and analysis of data provided by various areas of biological research.
Eukaryotes are contrasted with the prokaryotes (see Monera Monera, taxonomic kingdom that comprises the prokaryotes (bacteria and cyanobacteria).
Prokaryotes are single-celled organisms that lack a membrane-bound nucleus and usually lack membrane-bound organelles (mitochondria, chloroplasts; see cell, in biology).

 PROKARYOTE — EUKARYOTE ASSOCIATIONS IN SULFIDIC ENVIRONMENTS AND THEIR POSSIBLE EFFECTS ON S-CYCLING AND THE GEOLOGIC ...
While SOB-eukaryote symbioses were first described from hydrothermal vent taxa (e.g., tube worms, mussels), a plethora of additional prokaryotic-eukaryote symbioses have subsequently been described from other sulfide-enriched environments.
The majority of these eukaryotes have prokaryotic associates, or symbionts, many of which are sulfide-oxidizing bacteria (SOB).
While some anaerobic protists are known to have sulfate reducing symbionts and metazoans typically have sulfide-oxidizers, notable exceptions to this generality exist (e.g., sulfate reducer on metazoan).

 Eukaryote - Wikipedia, the free encyclopedia
In contrast, other organisms, such as bacteria, lack nuclei and other complex cell structures; such organisms are called prokaryotes.
In most eukaryotes, the proteins may be further modified in stacks of flattened vesicles, called Golgi bodies or dictyosomes.
Instead, some eukaryotes have obtained them from others through secondary endosymbiosis or ingestion.

 More on Eukaryote Morphology
However, the eukaryote flagellum is completely different in structure from that of a bacterium; some scientists prefer to use the word "undulipodium" for a eukaryotic flagellum, to emphasize this difference.
This may also be the case with MTOCs, although the evidence is less clear in this case.
An undulipodium is a bundle of nine pairs of microtubules surrounding a central pair (the so-called 9+2 structure).
