2. Eukaryotes are organisms made up of cells that possess a membrane-bound nucleus (that holds DNA in the form of chromosomes) as well as membrane-bound organelles. Eukaryotic organisms may be multicellular or single-celled organisms
3. Other Eukaryotes include plants, fungi, and protists.
4. Eukaryotes have many cellular characteristics that distinguish them from prokaryotes like bacteria
5. For example, all Eukaryotes have complex organelles, including a cytoskeleton, a membrane-bound nucleus and other membrane-bound organelles like mitochondria, the Golgi apparatus and chloroplasts.
6. Eukaryotes are cells commonly identified by the presence of a nucleus. Eukaryota is one of the three domains of life (bacteria and archaea are the others and collectively referred to as prokaryotes) and encompasses single-celled organisms as well as all multicellular life.

10. Eukaryotes are cytologically distinct from prokaryotes (archaeobacteria and eubacteria)
11. A typical eukaryotic cell contains membrane-bound intracellular structures such as a nucleus, mitochondria, and, for photosynthetic Eukaryotes, chloroplasts.
12. The oldest fossil clearly related to modern Eukaryotes is a red alga dating back to 1.2 billion years ago
13. Some time within Proterozoic Eon, then, all three major groups of life – Bacteria, Archaea, and Eukaryotes – became well established.

14. Eukaryotes include protoctists, fungi, plants, and animals.
15. Eukaryotes are distinguished from Archaea and Eubacteria in many different ways, but most importantly, the cells of Eukaryotes display a much greater degree of structural organization and complexity
16. Other microbial Eukaryotes were also observed, including the trichomonad Simplicimonas and the Apicomplexan Eimeria
17. Animals, plants, algae and fungi are all Eukaryotes
18. There are also Eukaryotes amongst single-celled protists.
19. Eukaryotes include larger, more complex organisms such as plants and animals
20. Only Eukaryotes have membrane-bound organelles and a nucleus
21. Eukaryotes reproduce sexually through meiosis, which allows for genetic variance.
22. We will shortly come to see that this is significantly different in Eukaryotes
23. See for more details the differences between prokaryotes and Eukaryotes
24. Eukaryotes can be single celled or mulitceullular (such as a dog)
25. Eukaryotes - Cells with Parts This is the place to learn about cells with a nucleus and all sorts of organelles
26. Eukaryotes are what you think of when you think of a classic "cell." There are cells without organized nuclei or organelles that are called prokaryotes, but not on this page.
27. Eukaryotes are more complex and much larger than the prokaryotes
28. Structurally, Eukaryotes possess a cell wall, which supports and protects the plasma membrane
29. In Eukaryotes, several factors are used in chain initiation such as eIF2, eIF3, eIF4A, eIF4E, eIF4F and elF 4G
30. Enzymes Involved: In Eukaryotes, two types of enzymes are used in
31. From prokaryotes to Eukaryotes Living things have evolved into three large clusters of closely related organisms, called "domains": Archaea, Bacteria, and Eukaryota
Eukaryotes, Evolved, Eukaryota
32. Eukaryotes will also have other membrane-bound structures that you will not see in prokaryotes
33. Eukaryotes are the third domain of life
34. Prokaryotes might be able to eat almost anything, but these Eukaryotes have other advantages
35. The Eukaryotes are a sophisticated bunch
36. Even the uni-cellular Eukaryotes, such as amoebas and yeast, have an intracellular complexity that far exceeds the simple machinery inside prokaryotes, classified as the “non-Eukaryotes.”
Even, Eukaryotes, Exceeds
37. The revised classification of Eukaryotes
38. Eukaryotes have a separate membrane bound nucleus, numerous mitochondria and organelles
39. The lack of internal membranes in prokaryotes distinguishes them from Eukaryotes.
40. In Eukaryotes and archaea, transcription initiation is far more complex
41. In Eukaryotes, a collection of proteins called transcription factors mediate the binding of RNA polymerase and the initiation of transcription.
42. This Amoeba Sisters video starts with providing examples of prokaryotes and Eukaryotes before comparing and contrasting prokaryotic cells with eukaryotic cel

43. Eukaryotes only appear in the fossil record later, and may have formed from endosymbiosis of multiple prokaryote ancestors
44. The oldest known fossil Eukaryotes are about 1.7 billion years old
45. However, some genetic evidence suggests Eukaryotes appeared as early as 3 billion years ago.

The largest of category eukaryotes is the animal kingdom. Animals are made up of complex cells, have tissue and organ systems and use sexual reproduction. More than 1 million species fall into this biological kingdom, including birds, fish, reptiles, amphibians, insects, worms, mollusks, jellyfish and sponges.
