- Q: What is an Eukaryotic Organism?
- A: An eukaryotic organism is a type of organism whose cells have a nucleus enclosed by a membrane and other membrane-bound organelles. Eukaryotes are characterized by their larger and more complex cells compared to prokaryotic organisms, which do not have a nucleus or membrane-bound organelles.
Eukaryotic organisms include animals, plants, fungi, and protists. These organisms are distinguished by their cellular structure and organization, as well as their ability to perform more complex functions such as mitosis, meiosis, and sexual reproduction.
In eukaryotic cells, the nucleus contains the organism's genetic material, which is organized into chromosomes. The cytoplasm surrounds the nucleus and contains various organelles, including mitochondria for energy production, ribosomes for protein synthesis, and the endoplasmic reticulum and Golgi apparatus for the processing and transport of proteins.
Eukaryotic organisms have evolved over billions of years and exhibit a wide range of adaptations and complexities, from the simplest unicellular organisms to the largest multicellular organisms.

- Eukaryota, whose members are known as eukaryotes, is a diverse domain of organisms whose cells have a nucleus. All animals, plants, fungi, and many unicellular organisms are eukaryotes. They constitute a major group of living things, along with the two groups of prokaryotes, the Bacteria and the Archaea.
The eukaryotes emerged in the Archaea, possibly as a sister of the Asgard archaea. This implies that there are only two domains of life, Bacteria and Archaea, with eukaryotes incorporated among the Archaea. Eukaryotes represent a small minority of the number of organisms, but, due to their generally much larger size, their collective global biomass is about equal to that of prokaryotes. Eukaryotes emerged approximately 2.2 billion years ago, during the Proterozoic eon, likely as flagellated cells. These were created by symbiogenesis between an anaerobic Asgard archaean and an aerobic proteobacterium, which formed the mitochondria. A second episode of symbiogenesis with a cyanobacterium created the plants, with chloroplasts.
Eukaryotic cells contain membrane-bound organelles such as the nucleus, the endoplasmic reticulum, and the Golgi apparatus. Eukaryotes may be either unicellular or multicellular. In comparison, prokaryotes are typically unicellular. Unicellular eukaryotes are sometimes called protists. Eukaryotes can reproduce both asexually through mitosis and sexually through meiosis and gamete fusion.
