USABO Latest Update with Verified Solutions Eukaryote An organism whose cells contain complex structures enclosed within membranes. The defining membrane bound structure thats sets them apart from prokaryotic cells is the nucleas or nuclear envelope within which the genetic material is carried. All species of large complex species are eukaryotes, including animals, plants and funghi. Euchromatin This shows as pale areas in the nucleas under electro magnification. It is a less densly...

Bacteria - Single-celled organism that do not have a cell nucleus and the membrane-enclosed intracellular structures found in most other cells (Prokaryotic cell). Gram-positive Bacteria - Thick layer of peptidoglycan (20-80nm across). The peptidoglycan layer is closely attached to the outer surface of the cell membrane. Retains crystal violet stains. Lack an outer membrane and a periplasmic space. Gram-negative Bacteria - Cell wall is thinner, but more complex. Only 10-20% peptidoglycan. C...
