In Hinduism what does the term "nirvana" mean? And the answer cannot be the grunge band led by Kurt Cobain.

What is the difference between prokaryotic cells and eukaryotic cells?
Prokaryotic cells are simple cells that lack the complexity of eukaryotic cells. Prokaryotic cells do not have a nucleus, have only one chromosome, are usually unicellar, and do not have a true membrane. Examples of prokaryotic cells are bacteria and archaea. In contrast, eukaryotic cells are more complex, have a nucleus, more than one chromosome is present, typically multi-cellular organisms, and the cells have a true membrane. Examples of eukaryotic cells are animal and plant cells.
