(D) The secondary cell wall is formed inside the primary cell wall as the cell matures. It is primarily composed of cellulose,hemicellulose,and lignin. Lignin deposition is a characteristic feature that provides mechanical strength and rigidity to the secondary wall,distinguishing it from the primary wall. Therefore,the deposition of these substances,particularly lignin,contributes to the formation of the secondary cell wall.
