Cell Types

The different cell types can be classified into two categories according to their core organization.

  • Prokaryotic cells - does not have a membrane surrounding the nucleus, so the nuclear content remains mixed with the other cellular components. The only ones in this group are bacteria, cyanophytes and mycobacteria.
  • Eukaryotic cells - In the nucleus of the eukaryotic cell is stored the genetic material and around the nucleus there is a membrane that separates it from the cytoplasm.

In the cytoplasm of these cells can be found several membrane structures.
