What are the names of cells that do not have a formed nucleus? what are the cells with a formed nucleus called?

There are two types of living cells. The first type is prokaryotic cells, which were the first to appear on our planet. They do not have a formed nucleus, lysosomes, the Golgi complex and other elements that have a shell. But of course there is DNA in these cells. Genetic information moves freely within the cell. Simplicity has helped this type of cell to survive to our time. Another type of cells that have a formed nucleus are eukaryotes. These are more complex cells that evolved from prokaryotes.
