Answer 2

discuss how the cell nuclei evolved in prokaryotic and eukaryotic cells

Answer 3

in your las t post you were provided with a source of information:
http://evolution.berkeley.edu/evolibrary/article/_0/endosymbiosis_03
in order for you to utilize the facts and discuss the evolution of prokaryotes to eukaryotes.
Story short, the prokaryote cells (such as bacteria) have a fairly simple composition, pretty much a membrane and a cell wall, with a circular stand containing their genes.
Being the Eukaryote cells more complex, the posses DNA in the Nucleus and they also posses the mitochondria, an organelle that allows the cell to produce chemical energy.

The very fact you have to discuss, and I quote:
"Evidence supports the idea that eukaryotic cells are actually the descendents of separate prokaryotic cells that joined together in a symbiotic union. In fact, the mitochondrion itself seems to be the "great-great-great-great-great-great-great-great-great granddaughter" of a free-living bacterium that was engulfed by another cell".

Answer 4

Here's another link (from the same source) that explains in more detail, the endosymbiosis:
