i got this paragraph from the library on this site: The membrane that surrounds the http://www.answers.com/topic/cytoplasm of a cell; it is also called the plasma membrane or, in a more general sense, a unit membrane. This is a very thin, semifluid, sheetlike structure made of four continuous monolayers of molecules. The plasma membrane and the membranes making up all the http://www.answers.com/topic/intracellular membranous http://www.answers.com/topic/organelle display a common molecular architectural pattern of organization, the unit membrane pattern, even though the particular molecular species making up the membranes differ considerably. All unit membranes consist of a http://www.answers.com/topic/bilayer of lipid molecules, the polar surfaces of which are directed outward and covered by at least one monolayer of nonlipid molecules on each side, most of which are protein, packed on the http://www.answers.com/topic/lipid-bilayer surfaces and held there by various http://www.answers.com/topic/intermolecular-force. Some of these proteins, called http://www.answers.com/topic/intrinsic proteins, traverse the bilayer and are represented on both sides. The segments of the http://www.answers.com/topic/polypeptide chains of these http://www.answers.com/topic/myelitis-1 proteins within the core of the lipid bilayer may form channels that provide low-resistance pathways for ions and small molecules to get across the membrane in a controlled fashion. Sugar moieties are found in both the proteins and http://www.answers.com/topic/lipid of the outer half of the unit membrane, but not on the inside next to the cytoplasm. The molecular composition of each lipid monolayer making up the lipid bilayer is different. The unit membrane is thus chemically http://www.answers.com/topic/asymmetric.

What else can I help you with?
Is phospholipid one of the structured lipid found in cell membranes?
Yes,they are found in plasma membrane.They form the basic structure.
What are the basic type of membrane?
the basic type of membrane according to cell biology is a lipid bilayer with proteins embedded in it. most membranes are made this way except for difference in some biomolecules but the basic structure is the same that is a lipid bilayer with proteins embedded in it
Are phospholipids found in the cell membranes of animal cells?
yes, they are orgranized in the bilayer of the plasma membrane.
Are primary water-insoluble components of cell membranes?
The primary water-insoluble components of cell membranes are phospholipids, which have a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail. These phospholipids form a bilayer structure that makes up the basic framework of the cell membrane. Additional components like cholesterol and proteins are also present in cell membranes to provide structure and functionality.
Do protist have cell membranes?
Yes, protists have cell membranes. Cell membranes are present in all living cells, including those of protists, to regulate the passage of materials into and out of the cell and maintain cellular structure and function.
Is organism the cell the basic unit of structure?
The cell is the basic unit of structure of an organism.
What do phospholipids form?
Phospholipids form the basic structure of cell membranes. They have a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails, which arrange themselves in a bilayer to provide a barrier that separates the interior of the cell from its external environment.
What cell organelles lack membranes as part of their structure?
Ribosomes and centrioles are cell organelles that lack membranes as part of their structure. Ribosomes are responsible for protein synthesis, while centrioles play a role in cell division.
Do plants have a cell membrane?
Plant cells do have cell membranes, which are covered by the cell walls.
Is a cell membrane a plant structure or animal structure?
Cell membranes are found surrounding both plant and animal cells
What has the author Roger Harrison written?
Roger Harrison has written: 'Biological membranes, their structure and function' -- subject(s): Cell membranes, Membranes, Membranes (Biology)
Which macromolecule forms a double layer as the primary structure of cell membranes?
Phospholipids form the lipid bilayer that are the basis of cell membranes.
