Each membrane is a phospholipid bilayer with proteins embedded in it.
This description applies to all membranes, the internal ones as well as the plasma membrane (the one surrounding the cytoplasm).

Cell membranes consist of lipid bilayers that regulate what enters and exits the cell. Cell membranes also provide protection and support to the cell.
The protein molecules in the cell membrane consist of adenine, 5 carbon sugars and three phosphate groups.
do protists have cell membranes?
Every microbe has cell membranes but only plants have plasma membranes...
Yes all cells have cell membranes
The Cell Membrane
Membranes suspended in cytoplasm within a eukaryotic cell. These cells can be found in both plants and animals.

Which of these have very thin cell membranes?
Membranes
Plants have cell membranes just inside their cell walls. The cell membranes control what passes into and out of the cell.
The cell wall in a plant cell maintains the shape of the plant cell. It also supports and protects the cell. Animal cells do not consist of cell walls they only have a cell membranes. Hope that helped :)
Phopholipids - They have a hydrophillic head that is positioned to the inside of the cell and the outside environment. They also have hydrophobic tails that point towards each other inside the membrane. This is why cell membranes are referred to as lipid bilayers. They are 2 layers of phospholipids organzied by their interaction with water.
Cell membranes are not hard at all they are actually quite softish....
