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.

That is the cell wall.It is a non living organell which protects and supports the cell.

For plant cells, they have a cell membrane and covering the cell membrane is a cell wall. The cell wall is for the structure of the plant. For animal cells, they just have a cell membrane.
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.
The cell wall is a rigid supporting structure.
