This structure is called a cell wall and it is found in plant cells and bacteria cells.
The difference between a gram positive and gram negative bacteria is the thickness/presence of the peptidoglycan layer secreted on the outside of the plasma membrane
Cell Wall
Tails are Hydrophobic
In the plant cell, the membrane is the outside cover and regulates what comes in and out of the cell.
This is the cell wall. In bacteria it is made of peptidoglycan and in plants it is made of cellulose.

Membranes do not have a stiff outside. I suspect the answer you are looking for is the cell wall, which is a stiff structure found outside the cell membrane of a plant cell, but separate from it.

The cell membrane is a membrane separating the inside of the cell from the outside environment. This structure is also known as the plasma membrane or the cytoplasmic membrane.
