Unlike the cell membrane, the cell wall is made of tough fibres (D).
The cell membrane is mainly composed of a lipid bilayer - which means it is flexible. Plant cell walls are made of cellulose, hemicellulose and pectin - which make the cell rigid.
the cell membrane is as flexible barrier outside of the cell.

The cell membrane acts as a barrier between a cell and its environment. This is composed of a phospholipid bilayer. The hydrophilic phosphate heads face outside and the hydrophobic lipid tails point towards each other in the centre of the membrane.

It is a thin, flexible barrier that regulates what goes out and into the cell.

The cell membrane is selectively permeable. It is also very flexible and contains many different substances within it and on it, such as various proteins, lipids, cholesterol, etc, nicknaming it the fluid mosaic model.
Membrane or barrier that separates the nucleus from the rest of the cell.
