There is no true answer, only theories. It goes that the cell membrane in the early eukaryotes invaginated towards the nucleus more and more over time and finally just created a nuclear envelope in the cell. This allows the eukaryotic cell to control what molecules and proteins can enter and exit the nucleus via nuclear pores. The eukaryotes and prokaryotes split off in the evolution chain because a nucleus has advantages and having no nucleus has advantages too.

What is the difference of a prokaryote and a eukaryote?
Prokaryotes lack a nucleus and membrane-bound organelles, while eukaryotes have both a nucleus and membrane-bound organelles. Prokaryotes are usually unicellular and simpler in structure, while eukaryotes can be unicellular or multicellular and have more complex cellular organization.
Does prokaryote cells have a distinct nucleus?
No prokaryote cells do not have a distinct nucleus. The prokaryotes are a group of organisms whose cells lack a membrane-bound nucleus. Organisms whose cells do have a nucleus are called eukaryotes.
Which cell has a nucleus a eukaryote or prokaryote?
Only Eukaryotes have a Nucleus. However, Prokaryotes have a Nucleoid, a nucleus-like organelle that does not have a nuclear envelope or a nucleolus.
Eukaryote s lack a nucleus and other membrane organelles?
No, eukaryotes do have a true nucleus and organelles. What you're describing is a prokaryote.
A bacteria can be classified as a eukaryote?
No, bacteria are prokaryotes, not eukaryotes. Eukaryotes have membrane-bound organelles and a nucleus, while prokaryotes do not have these structures.
What does eukaryotes have that prokaryote does not?
cells with a nucleus
Why are eukaryote and prokaryote cells differ?
Eukaryotes have a nucleus. Prokaryotes do not have a nucleus.
Is bacteria eukaryotes or prokaryote?
Prokaryote because it lacks a cell nucleus
What is the difference betrween archaea and eukaryotes?
Archaea are prokaryote, which means that they do not contain a true nucleus, unlike eukaryotes that does.
What organelles do eukayote cells have that prokaryote cells dont?
Prokaryotes do not have an organized nucleus, eukaryotes have nucleus
What is the difference of a prokaryote and a eukaryote?
Prokaryotes lack a nucleus and membrane-bound organelles, while eukaryotes have both a nucleus and membrane-bound organelles. Prokaryotes are usually unicellular and simpler in structure, while eukaryotes can be unicellular or multicellular and have more complex cellular organization.

Which cell has a nucleus a eukaryote or prokaryote?
Only Eukaryotes have a Nucleus. However, Prokaryotes have a Nucleoid, a nucleus-like organelle that does not have a nuclear envelope or a nucleolus.
Are you a prokaryote or eukaryote"?
Prokaryotes are simple cells without a nucleus, while eukaryotes are complex cells with a nucleus. Which type are you?
Are eukaryotes made out of cells?
One prokaryote ate another smaller prokaryote, causing the smaller prokaryote to become the nucleus and the larger one is the cell itself.
Eukaryote s lack a nucleus and other membrane organelles?
No, eukaryotes do have a true nucleus and organelles. What you're describing is a prokaryote.
How is DNA in prokaryote different from the DNA in eukaryote?
DNA in eukaryotes is located in the nucleus- @p3x
