A typical cell ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

A typical cell 2 types of cell: Prokaryotes are not as structurally complex as eukaryotes, and were thought not to have any compartments enclosed by lipid membranes . In the past they were often viewed as having little internal organization, but slowly details are emerging about prokaryotic internal structures Eukaryotes are the most structurally complex known cell type, and by definition are in part organized by smaller interior compartments, that are themselves enclosed by lipid membranes that resemble the outermost cell membrane .

the structure of a cell membrane It is mainly composed of a lipid bilayer of phospholipid molecules but with a large numbers of protein molecules protruding the layer. LIPID BILAYER is the basic structure of the cell membrane. It is composed entirely of phaopholipid s and cholesterol. Interspersed in this lipid film are large globular protein molecules. Most of the membrane proteins are glycoproteins.
