The plasma membrane is a dynamic structure. It is composed of 2 layers of lipid material with protein molecules interspersed through out. The phospholipids move at a rate of 2um. /sec. while the proteins move at a much slower rate. The phospholipids have 2 definite ends, a hydrophilic (focusing to the outside and inside of the membrane) and a hydrophobic one (forming the center of the membrane

Lipids
The intrinsic properties of the hydrophilic/hydrophobic/hydrophilic double layer of the membrane gives it support, due to the hydrophobic effect.
Plasma membrane is made of two layer of phospholipids. The outer layer is hydrophilic while inside the membrane is hydrophobic therefore plasma membrane is not a hydrophobic barrier -it regulates what enters and leave the cell.
That would be phospholipids. They are a major component of the plasma membrane and contain hydrophilic, as well as, hydrophobic properties.
phospholipids are the molecules that make up the plasma membrane and they are made of polar (hydrophilic) heads and 2 non-polar (hydrophobic) tails
The continuous part of the plasma membrane is the outer layer.
The "head" of the membrane, the phosphate.
The intrinsic properties of the hydrophilic/hydrophobic/hydrophilic double layer of the membrane gives it support, due to the hydrophobic effect.
"philic" ( likes water)
The parts of the plasma membrane (I am assuming that you are referring to the plasma membrane) are hydrophilic (water-loving) heads, hydrophobic (water-hating) tails, cholesterol, carb chains, and integral proteins. The plasma membrane is known to be fluid-mosaic, meaning that its motion is wave-like. The hydrophilic head is located on the very outside of the plasma membrane and the inside of the cell. The hydrophobic tails are located in between the two hydrophilic heads. The cholestrol is located inside the plasma membrane to not allow the tails to be tangled. Carb chains are located outside of the plasma membrane (along with hydrophilic heads) and is there for chemical ID of the cell. Integral proteins are also located outside the plasma membrane; its function to shape materials needed inside the cell to a certain shape (diffusion). hydrophilic head-> OO <- hydrophilic head hydrophobic tails---------^

the hydrophilic easier than hydrophobic substances
That would be phospholipids. They are a major component of the plasma membrane and contain hydrophilic, as well as, hydrophobic properties.

The continuous part of the plasma membrane is the outer layer.
That is the structure of plasma membrane adjectent or near the secondary cell wall in a cells. It's a living outermost boundary of all the cells.
It is the plasma membrane of a cell. The plasma membrane is a phospolipid bilayer, but because the phospsolipids are amphipathic, and because the lipid tails of each are turned into one another it is considered a trilamina. Hydrophilic Head of the inner layer + lipid tails of each layer + Hydrophilic Head of the outer layer.
A polar molecule is hydrophilic, which means that it will easily dissolve in water. Examples of hydrophilic molecules are sugars and salts.
