Cell membranes contain a variety of biological molecules, notably lipids and proteins. Material is incorporated into the membrane, or deleted from it, by a variety of mechanisms:
- Fusion of intracellular vesicles with the membrane (exocytosis) not only excretes the contents of the vesicle but also incorporates the vesicle membrane's components into the cell membrane. The membrane may form blebs around extracellular material that pinch off to become vesicles (endocytosis).
- If a membrane is continuous with a tubular structure made of membrane material, then material from the tube can be drawn into the membrane continuously.
- Although the concentration of membrane components in the aqueous phase is low (stable membrane components have low solubility in water), there is an exchange of molecules between the lipid and aqueous phases.

YHURRR WELCOME!!!! I'm mean please say thanks :)Wiki User

Does prokaryotic or eukaryotic cells contains plasma membrane?
Both eukaryotic cells and prokaryotic cells have a plasma membrane.
A plasma membrane is most fluid if it contains?
Unsaturated fatty acids
What contains cell materials?
The plasma membrane-- AKA the cell membrane-- surrounds the cell and keeps the cytoplasm and organelles in the cell.
How does nutrients enter a cell?
The plasma membrane.
Which cell contains membrane proteins en- abling a hormone to selectively bind to its plasma membrane?
The cell membrane contains the membrane proteins that enable a hormone to selectively bind to its plasma membrane. These proteins, such as receptor proteins, are responsible for recognizing and binding to specific hormones, allowing the hormone to exert its effects on the cell.
Does prokaryotic or eukaryotic cells contains plasma membrane?
Both eukaryotic cells and prokaryotic cells have a plasma membrane.
What contains the chloroplast?
Chlororplast contains a surface area plasma membrane and endoplasmic memranes.

Another name for plasma membrane?
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
What part of a sperm cell contains enzymes that weaken the plasma membrane of the egg?
Acrosome
What does the chloroplast contain?
Chlororplast contains a surface area plasma membrane and endoplasmic memranes.
The plasma membrane is made chemically of a molecule that has both?
The plasma membrane is made up of phospholipids, each of which contains a glycerol molecule bonded to a phosphate group and two fatty acids.
What is the definition of animalcell?
Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane. It contains a membrane bound nucleus and organelles.
The plasma membrance of a cell consists of?
The plasma membrane consists of a phospholipid bilayer that contains proteins. There are four types of proteins in the plasma membrane - structural protein, receptor protein, transport protein and glycoprotien.
