The cell membrane is formed from a phospholipid bilayer, with the hydrophobic lipid portions (the tails) on the inner portion and the hydrophilic portion of the phospholipid (the heads) facing the inner and outer surfaces. There are also proteins in the cell membranes.
Phospholipids
They are both double membraned / a double unit membrane
a carrier
The cell membrane is semi-permeable controlling the movement of substances in and out of the cell. It contains a phospholipid bilayer consisting of hydrophobic tails and hydrophilic heads. Also contained in the cell membrane are transport proteins.
simple squamous
cell membrane is single whereas the nuclear membrane is double, hence it is also called nuclear envelop.
I think you're thinking of lipids, the things with the hydrophobic tail and the hydrophillic head? I think that's it.
The double membrane which surrounds the nucleus of a Eukaryotic cell.
The plasma membrane is a bi-layer, so yes.
A cell membrane lets nutrients into the cell. The nucleus is like the brain of the cell.
