Answer:It evolved from prokaryotes and has a nucleus.
Step-by-step explanation:
Eukaryotes are a diverse group of organisms that include plants, animals, fungi, and protists. They evolved from prokaryotic ancestors through a process known as endosymbiosis. This process involved one prokaryotic cell engulfing another, forming a symbiotic relationship where the engulfed cell evolved into an organelle, such as mitochondria or chloroplasts, within the host cell. This led to the development of eukaryotic cells with a well-defined nucleus and various other membrane-bound organelles, which distinguish them from prokaryotic cells. Eukaryotes can be unicellular or multicellular organisms.
