Two layers of phospholipids are arranged as a bilayer that forms the basis of cell membrane structure. One layer has its hydrophilic heads neighbouring the surroundings whereas the other has its hydrophilic heads neighbouring the cytoplasm. The hydropholic fatty acid tails of both layers of phospholipid point towards the centre.

∙ 13y agosimple answer - it is a non-polar layer. so polar molecules are not able to pass through it easily. they need to be actively or passively transported across. non-polar molecules are able to just move through.

∙ 11y agoThe cytoplasmic membrane is a bilayer of phospholipids that has polar and nonpolar parts. Each polar part has a head that contains phosphate and is hydrophilic ("water-loving"). Each nonpolar part has two tails composed of long fatty acids that are hydrophobic ("water-fearing"). The heads always face outwards to a watery fluid such as the extracellular fluid on the outside of the cell and the intracellular fluid inside the cell. Tails align back to back preventing the watery fluid from crossing the cytoplasmic membrane.

What form the majority of the plasma membrane of cells?
phospholipids
What is in the center of the plasma membrane?
The lipid tails are found in the centre of the membrane. The membrane is made out of phospholipids. These have a phosphate head which is hydrophilic and a lipid tail that is hydrophobic. This form a bilayer (double-layer).
What lipids forms a bilayer between watery region in the plasma membrane of a cell?
I believe you are referring to phospholipids. They form a bilayer around the plasma membrane of the cell to keep the cellular contents in and selectively allow things to come in and out of the cell.
What makes it possible for the plasma membrane to self assemble?
The plasma membrane is able to self-assemble due to the properties of its constituent molecules, such as phospholipids. Phospholipids have hydrophilic heads and hydrophobic tails, which drives them to form a bilayer structure when exposed to water. This spontaneous assembly is driven by the hydrophobic effect and results in the formation of a stable and selectively permeable membrane.
What kind of lipids make up the bilayer that form the membrane?
Phospholipids
What form the majority of the plasma membrane of cells?
phospholipids
What form the majority of the plasma membrane of cells.?
Phospholipids
What 2 molecules make up the cell membrane?
The plasma membrane is flexible and is made up of organic molecules called lipids and proteins .
Because cells have a watery environment bothinside and outside the polar ends of the phospholipids in the plasma membrane from layer?
Because cells have a watery environment both inside and outsidethe polar ends of the phospholipids in the plasma membrane form layers?
What is the important function of the phospholipids in the cell membrane?
They make up the plasma membrane and provide flexibility and protection to the plasma membrane. They also form a semi-permeable membrane, therefore making it easy for water to go in an out (osmosis).
What is in the center of the plasma membrane?
The lipid tails are found in the centre of the membrane. The membrane is made out of phospholipids. These have a phosphate head which is hydrophilic and a lipid tail that is hydrophobic. This form a bilayer (double-layer).
The fundamental structure of the plasma membrane is determined almost exclusively by?
Lipids, in the form of the bi-lipid layer.

What molecules form much of the cell membrane?
The cell membrane is composed mainly of lipids. Phospholipids to be precise.
What are the different lipids that are in cell membrane?
Phospholipids are found in the cell membrane which form the bilayer
What is a double layer of phospholipids?
A cell's membrane (plasma membrane) is made of a phospholipid bilayer where the hydrophillic phosphate groups form the two outer sides of the bilayer and the hydrophobic fatty acid chains are the interior.
