Question

The secondary cell wall is the thickest and provides the greatest strength to the cell. It is made up of cellulose microfibrils embedded in a matrix of lignin, which provides rigidity and strength to the cell wall. The primary cell wall is thinner and more elastic, while the middle lamella is made up of pectin and acts as a glue between adjacent cells rather than providing structural strength. The plasma membrane is not part of the extracellular matrix but rather the boundary between the cell and its environment.
