The fluid mosaic model of cell membrane is:
Correct answer: A. Phospholipid bilayer having scattered proteins
- A. Phospholipid bilayer having scattered proteins
- B. Phospholipid bilayer is enclosed in protein layer
- C. Carbohydrate chains are attached with phospholipid bilayer
- D. In which protein molecules are free to move about in a fluid bilayer of phospholipid molecules
Explanation
The model proposes that the membrane is a phospholipids bilayer in which protein molecules are either partially or wholly embedded. The proteins are scattered throughout the membrane in an irregular pattern just like large ice bergs float in the sea.

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.
