Plasama membrane is adjecent or near the secondary cell wall in a cell. It is a living outermost boundary of all the cells. ULTRA STRUCTURE: It consist of three layer that is two protein layers on either side and a double middle layer of phospholipids. The conteneous layer of proteins sandwich the central phospholipid bilayers. Recently Singer and Nicholson proposes the fluid mosaic model of plasma membrane which states that there are two types of protein found in P.M. 1 Periheral or extrinsic protein : which is loosley bound to the lipid layer and is of floating type. It can be remove easily. 2 Integral or intrinsic protein: they are embeded in central phospholipid bilayers attached with oligosaccharide and can not remove easily. Carbohydrates are also present in plasma membrarne mainly bound to glycoprotein and also to glycolipids. Carbohydrate mainly in glycoprotein play an important role in cell that is cell recognization.

What is the bacterial structure that acts as a selective barrier allowing nutrients to enter the cell and wastes to leave the cell.?
plasma membrane
Which structure regulates passage of molecules into and out of cells?
The cell membrane is a membrane separating the inside of the cell from the outside environment. This structure is also known as the plasma membrane or the cytoplasmic membrane.
This structure is the outermost boundary of the cell and is semipermeable?
Plasma membrane or cell membrane
Which cell structure is represented by the three- dimensional?
Cytoskeleton is 3d structure.It is spreaded through out the cell.
What is the structure that surrounds a cell and controls what enters and leaves the cell?
The structure that controls traffic to and from the cell is the plasma membrane. It is not to be confused with the cell wall, which serves more to give structure to the cell.
What structure is involved in phagocytosis?
Plasma Membrane !

Plasma membrane or cell membrane
Can you clearly see the membrane as a structure?
Yes, the cell membrane can be seen clearly as a structure. The cell membrane is called the plasma membrane and is a barrier between the cell and its environment.
What is the structure of a plasma membrane and what is the role of their hydrophilic heads?
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.

that meand there no plasma membrene
What is a structure outside the plasma membrane?
cell wall cell wall
What important cellular structure is made mostly of phospholipids?
plasma membrane
What describes the plasma membrane?
It is a dynamic fluid structure that is in constant flux
