Detailed explanation-1: -So, the correct answer is ‘Lignin’.
Detailed explanation-2: -So, the correct answer is ‘Lignin’.
Detailed explanation-3: -1 Expert Answer Your assumption is correct as nucleic acids are not found in cell membrane. They are not a structural component in the cell membrane. They are only found in ribosomes and the nucleus as either DNA or RNA.
Detailed explanation-4: -Four major phospholipids predominate in the plasma membrane of many mammalian cells: phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and sphingomyelin. The structures of these molecules are shown in Figure 10-12.
Detailed explanation-5: -Each of these cells is a discrete structure surrounded by a cell membrane and filled with a thick solution called cytoplasm. In human cells, most DNA is found in a compartment within the cell called a nucleus.
