Fluid mosaic model was proposed by Singer and Nicolson. According to this model, there is a central lipid bilayer of phospholipids with their polar head group towards the outside and the non-polar tails pointing inwards. Some proteins are embedded in the lipid layer are called integral or intrinsic proteins and they cannot be separated from the membrane. There are large globular integral proteins which project beyond the lipid layer on both the sides. Superficially attached proteins are called extrinsic or peripheral proteins and can be easily removed. Some membrane lipids and integral proteins remains bound to oligosaccharides which project into the extracellular fluid.

Fluid Mosaic Model Overview
The fluid mosaic model is a widely accepted explanation of the structure of the plasma membrane. Proposed by S.J. Singer and Garth L. Nicolson in 1972, this model describes the membrane as a dynamic and flexible structure.
Key Components of the Fluid Mosaic Model
- Lipid Bilayer:
- Composed of phospholipids, where the hydrophilic (polar) head faces outward towards the aqueous environment, and the hydrophobic (non-polar) tails point inward.
- Integral Proteins:
- These proteins are embedded within the lipid bilayer and span across it. They are integral to the membrane's function and cannot be easily removed without disrupting the membrane structure.
- Extrinsic Proteins:
- Also known as peripheral proteins, these are loosely attached to the membrane's surface and can be removed without damaging the membrane.
- Carbohydrate Chains:
- Many membrane lipids and integral proteins have oligosaccharide chains attached to them, which extend into the extracellular space and play roles in cell recognition and signaling.
Correct Answer Explanation
The question asks who proposed the fluid mosaic model of the plasma membrane. The correct answer is:
- c) Singer and Nicolson:
- They formulated this model to describe the membrane's structure and function, highlighting its fluidity and the mosaic-like arrangement of proteins within the lipid bilayer.
By understanding this model, one can appreciate the complexity and functionality of cell membranes, which are crucial for maintaining homeostasis and facilitating communication between cells.
