The answer you're looking for is probably two, because a membrane consists of two layers of phospholipids, but it really depends on how the word "layer" is defined in this context.
What else can I help you with?
How many membranes are around the plasma membrane?
The plasma membrane is a bi-layer, so two.
What are the differences between the plasma membrane and other membranes?
plasma membrane and other membranes are the same
How many layer of plasma membrane circulate the ribosomes?
They do not have membranes. They are naked organelles
Plasma membranes consist of what kind of membrane?
A phospholipid bilayer.
What is the system of membranes and tubes connecting nuclear membrane and plasma membrane?
Endoplasmic Reticulum
What is the difference between cell surface membrane and plasma membrane?
The diffrence is that the cell membrane is just a barrier between the exterior enviroment and the interior of the cell, while the cell surface membrane exerts control over what enters/leaves the cell! :)
When vesicles from the Golgi apparatus deliver their contents to the exterior of the cell they add their membranes to the plasma membrane. The plasma membrane does not increase in size because?
The membrane is continually being lost from the plasma membrane by endocytosis

How plasma membrane diffuse across plasma membrane?
Ions can't diffuse across membranes, they must used channels to transport across
Do bacterial plasma membranes contain sterols?
Many bacterial plasma membranes do contain a sterol like membrane called hopanoids. Hopanoids are a natural pentacylic compound, this is based on the chemical structure hopane.
Are plasma membranes in every living cell?
Yes, Plasma membrane is present in every living cell.
Does all animal and plant have plasma membranes?
Yes,all of them have.Every living organism has a plasma membrane.
