Who proposed the fluid mosaic model of plasma membrane ?

Options

A. Camilla Golgi
B. Schleiden and Schwann
C. Singer and Nicolson
D. Robert Brown

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the scientists who proposed the fluid mosaic model of the plasma membrane.

2. **Identifying Key Information**: The fluid mosaic model is a widely accepted model that describes the structure of the plasma membrane. It was proposed in 1972.

3. **Recognizing the Scientists**: The fluid mosaic model was proposed by two scientists: Singer and Nicholson.

4. **Understanding the Model**: The fluid mosaic model describes the plasma membrane as a phospholipid bilayer with proteins embedded within it. The lipids exhibit a quasi-fluid nature, allowing for lateral movement, while proteins can exhibit flip-flop movements.

5. **Conclusion**: Therefore, the correct answer to the question is that the fluid mosaic model of the plasma membrane was proposed by Singer and Nicholson.

**Final Answer**: The fluid mosaic model of the plasma membrane was proposed by Singer and Nicholson in 1972.
