The plasma membrane is made up of two layers of:
Correct answer: B. Phospholipids
- A. Carbohydrates
- B. Phospholipids
- C. Cell wall
- D. Proteins
Explanation
The plasma membrane is made up of two layers of phospholipids, and hence called lipid-bilayer. The non-polar tails of both phospholipids face each other while the heads face towards the cytoplasm and extracellular space.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
