What was the unit membrane model?
Correct answer: A. Plasma membrane has lipid bilayer sandwiched between two outer layer of protein.
- A. Plasma membrane has lipid bilayer sandwiched between two outer layer of protein.
- B. Proteins are embedded in the lipid bilayer
- C. Plasma membrane has charged pores for transport of materials which cannot penetrate through the lipid bilayer
- D. All of the above
Explanation
It was proposed earlier that a cell membrane is composed of a lipid bilayer sandwiched between inner and outer layers of protein. This, basic structure is called the unit membrane and is present in all the cellular organelles.

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.
