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 packed form of chromatin; 10% is even less cond...
