Eukaryotic cell anatomy
WebTheir chromosome—usually single—consists of a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane. The cell wall functions as a protective layer, and it is responsible for the organism’s shape.

WebEukaryotic cell structure. Eukaryotic cell structure is much more complex than prokaryotic. Prokaryotes are also single-celled, so they can not "create" specialized structures. For example, in the human body, eukaryotic cells form tissues, organs and organ systems (e.g. cardiovascular system). Here are some structures unique to …
WebLike prokaryotes, eukaryotic cells have a plasma membrane ( [link] ), a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment.
