Verified step by step guidance

Understand the role of the plasma membrane: The plasma membrane is a biological membrane that separates the interior of all cells from the outside environment. It is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.

Identify the components of the plasma membrane: The plasma membrane is primarily composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates.

Recognize the function of cell surface markers: Cell surface markers are molecules present on the cell membrane that help in cell recognition and communication. They play a crucial role in the immune response and in the interaction between cells.

Differentiate between the options given: Lysosomes, mitochondria, and ribosomes are organelles within the cell, not components of the plasma membrane. Glycoproteins, however, are proteins with carbohydrate groups attached, which are found on the cell surface and act as markers.

Conclude that glycoproteins are the correct answer: Glycoproteins serve as cell surface markers on the plasma membrane, facilitating cell recognition and communication.
