Answer: Nuclear membrane
Explanation:
The extracellular matrix can be defined as the matrix that lies outside the cell. It includes all membranes or external coverings and fluid which separates the cell from its exterior. The extracellular matrix is important for adhesion, and communication between cell to cell. This helps the cell to connect with the other substratum. The cell wall is the external layer around the plant cell which separates the plant cell from its external environment. It maintains the structure of the plant cell. The cuticle is the thick layer of cells which separates the cells from the external environment. The basement membrane is sheet of cells that forms the part of extracellular matrix in the epidermis. The nuclear membrane is the part of the cell. It lies around the nucleus which is the component of the cell and not of extracellular matrix.
