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
Tails are Hydrophobic
Cell Wall
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.

While cell membranes might be around every cell, cell walls made of cellulose are only found around plant cells. There are other sorts of cell walls. Many but not all bacteria also have a structure called a cell wall.Fungi and some protozoa also have cell walls. These walls are made of proteins. They serve the same purpose of protecting and maintaining structure.
For plant cells, there is a cell wall outside of the cell's membrane. Animal cells do not have walls, so there is no structure outside of the cell membrane.

Plant cells have a cell wall made of cellulose, which provides structure and support, while bacteria have a cell membrane that surrounds their cytoplasm.

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.
