two. biphospholipid. bi (meaning two) phospho (refering to the phosphorous group) lipid (fatty acid).
the plasma membrane of a cells consists of two layers of phospholipids. now go look it up yourself and make sure this is correct instead of relying on a stranger.

∙ 15y agoThe basic cell membrane is a Phospholipid bilayer, which has some other molecules (proteins etc) in it. But, basically it is a Phospholipid bilayer. "Bi" means "two", therefore the cell membrane consists of two layers. A phospholipid structurally has a head part, which is polar, and hydrophilic (loves water), while the tail part is non-polar, and hydrophobic (hates water). Cells are sorrunded with extracellular fluid, and also, inside the cell, cytosol contains water as well. Therefore, the cell membrane needs hydrohilic (water loving) part facing these fliuds. To achieve that, it is consists of two layers, and that way, the head part faces the outside, intercellular fluid, and also the inner fluid, leaving the water-hater lipid tails safely between these too rows. These arrangement serves other purposes as well, like determining which and how could substances, molecules enter and leave the cell.

The cell membrane and the nuclear membrane are made of?
the cell membrane, also known as the plasm membrane, forms a boundary between a cell and the enviroment and is made of a double layer of phospholipids. A phospholipid is made of a charged phosphate group, a glycerol, and two fatty acid chains.
How many membrane layers cover the nucleus?
There isn't a specific number of membranes that a eukaryote has, mainly because it is unknown how many organelles are in a cell and how many cells are in an organism. A eukaryotic cell is surrounded by one plasma membrane, but most organelles within the membrane are also covered with membranes, sometimes two in case of mitochondria or chloroplast.
What characteristics make the cell membrane unique?
Cell Membrane is a semi-permeable part of a cell which takes part in exchanging enzymes, proteins or nutrients in between the environment and the cell. The Cell Membrane has a very lively effect to it and acts as a coating which also protects the cell in many ways.
Do any of the Cells lack a Cell membrane?
Yes, all cells have a cell membrane. A cell membrane is necessary because it controls what materials go in and out of a cell. Without it, many harmful products would go into a cell and the cell would be destroyed.
What does a cell wall surround?
Yes, animal cells are surrounded by a cell membrane. anything going in or out of the cell must go through the cell membrane.
How many cell layers make up the onion membrane?
2 layers
How many layers does a cell membrane contain?
71 microscopic layers
How many layers is the cell membrane and what is it made of?
2 layers of lipids.
How many layers of phosphilids does the cell membrane have?
2
How many phosphoipid layers does a cell membrane have?
There are 2, surrounding a water layer.

How many layers does the plasma membrane has?
Two phospholipid layers? I think.
How many cell layers do roundworms have?
forty-six layers
How many layers in a blood cell?
there are two layers inner and outer layer of a blood cell.......
How do the membrane proteins prevent subtances from entering or exiting or exiting the cell?
membrane proteins are like signals that require activation and energy (in this case ATP) much like most processes in the human body. membrane proteins exist between layers of other cells and can act as channels from one side of a membrane to another in many cases with out anything physically being transfered through the cell membrane.

What do cell membrane do that cell walls can't do?
Cell membrane is selectively permeable membrane, therefore it allows selective molecules to be taken in by the cell and excludes others. Whereas cell wall is permeable in nature and does not inhibit the intake of many molecules what the cell membrane does.
