The lipid bilayer has been firmly established as the universal basis for cell-membrane structure. It is easily seen by electron microscopy, although specialized techniques, such as x-ray diffraction and freeze-fracture electron microscopy, are needed to reveal the details of its organization. The bilayer structure is attributable to the special properties of the lipid molecules, which cause them to assemble spontaneously into bilayers even under simple artificial conditions.

FAQs
Which Molecule Has Both Hydrophilic And Hydrophobic Properties And Is Found In Plasma Membranes? ›
Phospholipids. Phospholipids, arranged in a bilayer, make up the basic fabric of the plasma membrane. They are well-suited for this role because they are amphipathic, meaning that they have both hydrophilic and hydrophobic regions. Chemical structure of a phospholipid, showing the hydrophilic head and hydrophobic tails ...
What has both hydrophobic and hydrophilic properties? ›A phospholipid is an amphipathic molecule which means it has both a hydrophobic and a hydrophilic component.
What are the hydrophobic and hydrophilic in the plasma membrane? ›The heads, which form the outer and inner linings, are "hydrophilic" (water loving) while the tails that face the interior of the cell membrane are "hydrophobic" (water fearing). Water is attracted to the outsides (red) of the membrane but is prevented from going through the non-polar interior (yellow) layer.
Why does the plasma membrane have to be both hydrophobic and hydrophilic? ›The amphipathic nature of the phospholipid bilayer allows for important properties of the cell membrane. For example, the hydrophobic nature of the tails promotes the selective permeability of the membrane. Large molecules or hydrophilic molecules are unable to pass through the bilayer without assistance.
Which of the following molecules found in the plasma membrane is made of both a hydrophobic tail? ›The fundamental building blocks of all cell membranes are phospholipids, which are amphipathic molecules, consisting of two hydrophobic fatty acid chains linked to a phosphate-containing hydrophilic head group (see Figure 2.7).
