cyclic nucleotides and deoxyribonucleic acid (DNA)
ribonucleic acid in some forms
four carbon rings fused together are a misconception of cell membrane but are actuall part of cell walls
A fence around your yard that has a gate to allow selective items in and is semipermiable and allows some things to pass through the holes in the chain links.
Cell Wall, as in plants. The cell membrane is actually inside of the cell wall. Under Microscopy one can observe the cell membrane pulling away from the cell wall in instances of dehydration.
A cell membrane is similar to the object you use as a balloon. It forms the wall around the cell and allows some things to come in and some to go out. It is a boundary.
The cell membrane controls movement of materials in and out of the cell.
The selective permeability of the cell membrane

the cell membrane is as flexible barrier outside of the cell.

Is this a serious question? The moon is a nonexample. My face is a nonexample.
where is the cell control membrane and the cell membrane
Cell membrane
in plants cell surface membrane! and in animal plasma membrane!
The outer edge of a plant cell is called the cell wall
