Detailed explanation-1: -Detailed Solution. The plasma membrane doesn’t have any type of Nucleic Acid-either DNA or RNA. The plasma membrane consists of lipids, cholesterol, phospholipid bilayer, glycol-lipids, etc.

Detailed explanation-2: -So, the correct answer is ‘Lignin’.

Detailed explanation-3: -Enclosed by this cell membrane (also known as the plasma membrane) are the cell’s constituents, often large, water-soluble, highly charged molecules such as proteins, nucleic acids, carbohydrates, and substances involved in cellular metabolism.

Detailed explanation-4: -The fundamental building blocks of all cell membranes are phospholipids, which are amphipathic molecules, consisting of two hydrophobic fatty acid chains linked to a phosphate-containing hydrophilic head group (see Figure 2.7).

Detailed explanation-5: -Lysosomes and vacuoles are the cell organelle in which do not have their own DNA.
