How many layers make up a cell membrane?

Answer 1

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.

Answer 2

The 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.
