Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The following are true of the cell’s plasma membrane, EXCEPT:

A	It is serves as the boundary that separates the intracellular components and the extracellular matter
B	Serves as site of attachment of cells to other cells
C	Composed of a single layer of phospholipids
D	Composed primarily of proteins and lipids, with small amounts of carbohydrates

Explanation:

Detailed explanation-1: -Cell membranes are composed of proteins and lipids. Since they are made up of mostly lipids, only certain substances can move through. Phospholipids are the most abundant type of lipid found in the membrane. Phospholipids are made up of two layers, the outer and inner layers.

Detailed explanation-2: -Final answer: Plasma membrane allows selected molecules to pass into and out of the cell.

Detailed explanation-3: -The plasma membrane is composed of a bilayer of phospholipids, with their hydrophobic, fatty acid tails in contact with each other. The landscape of the membrane is studded with proteins, some of which span the membrane. Some of these proteins serve to transport materials into or out of the cell.

Detailed explanation-4: -So, the correct answer is ‘Lignin’.
