The hydrophilic regions of a membrane protein are most likely to be found?
The hydrophilic regions of a transmembrane protein are likely to be found on the exterior of the membrane. The transmembrane protein may have three parts: a hydrophilic segment, a hydrophobic segment, and another hydrophilic segment. The hydrophobic region would be in between the hydrophilic regions. The hydrophobic region will be embedded in the membrane and the hydrophilic regions will be on the inside and outside of the membrane.
What molecules add support to plasma membrane?
The intrinsic properties of the hydrophilic/hydrophobic/hydrophilic double layer of the membrane gives it support, due to the hydrophobic effect.
Is the polar end of the phospholipid plasma membrane hydrophobic or hydrophilic?
A polar molecule is hydrophilic, which means that it will easily dissolve in water. Examples of hydrophilic molecules are sugars and salts.
Why are the head groups of the phospholipids found on the exterior and the cytoplasmic side of the membrane?
they are hydrophilic
Is the phospholipids bilayer symmetric?
No, it is asymmetric with hydrophilic portion on the outside and hydrophobic on the inside.

Which end of the plasma membrane is hydrophilic?
The "head" of the membrane, the phosphate.
Which portion of a fatty acid is hydrophilic?
Tail
These form the cell membrane by lining up tail-to-tail in a double row?
The cell membrane is formed from a phospholipid bilayer, with the hydrophobic lipid portions (the tails) on the inner portion and the hydrophilic portion of the phospholipid (the heads) facing the inner and outer surfaces. There are also proteins in the cell membranes.

What is the difference between diffusion of hydrophobic substances in comparison to hydrophilic ones across the plasma membrane?
the hydrophilic easier than hydrophobic substances

Is the phospholipids bilayer symmetric?
No, it is asymmetric with hydrophilic portion on the outside and hydrophobic on the inside.
In a plasma membrane is a hydrophilic portion oriented to the outside of the cell?
Yes, the phosphate head which are hydrophillic is facing outside the cell and inside the cell. (Its a bilayer of phospholipids, and the fatty acid tails(hydrophobic) face each other)
Three major parts of the cell membrane?
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---------^
