What is the function of the lipid bilayer in the cell membrane?

Answer 1

That is just another name for the cell membrane. It's main job is to keep the things that are on the inside of a cell inside, and keep what things are outside the cell on the outside. It is also called a semipermeable membrane because it can allow some things, under certain situations, to cross the phospholipid bilayer to enter or exit the cell.
The phsopholipid bilayer is the thin polar cell membrane comprised of two layers of lipids. This membrane surrounds a cell to keep substances (ions, proteins, etc) in or out of the cell, but also allow selected substances to pass through the cell membrane as required.

Answer 2

The lipid bilayer serves as barrier for most aqueous substances. It allows lipid-soluble material to pass through it. Glycolipids and glygoproteins in the bilayer help in recognition of substances outside the cell. Transmembrane proteins allow some aqueous materials to pass through.

Answer 3

It has many functions.

1. keeping the cell together - with all the organelles and such.

2. To help protect the inside from intruders.

3. Help things outside of the cell to go inside the cell and vice versa (the membrane gives permission if someone can go inside the cell or not)

Answer 4

Plasma membrane separates the cell from its surrounding environment. Molecules of the cell membrane are arranged in a sheet.
A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer Some membrane proteins have carbohydrates attached to them, forming glycoproteins that act as identification markers.

Answer 5

It serves as a barrier between the internal parts of the cell and the outside environment. However, it does allow some materials to transport across it, like oxygen.

Answer 6

It uses the surface tension of water (the monomolecular layer trapped between the two layers of fat) to hold the cell together.

Answer 7

give a cell it's shape and protect it from the extracellular space
