The fluid mosaic model of the cell membrane was first proposed by

Options

A. Robert Hooke
B. corti and funtena
C. Davson & Danielli
D. Singer and Nicolson

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the scientist who first proposed the fluid mosaic model of the cell membrane.

2. **Identifying the Options**: The options provided are Robert Hooke, Cartee and Fontana, Devson and Danilay, and Singer and Nicholson.

3. **Recalling Relevant Information**: The fluid mosaic model describes the structure of the cell membrane, highlighting the fluid nature of the lipid bilayer and the arrangement of proteins within it.

4. **Identifying the Correct Scientist**: The fluid mosaic model was specifically proposed by Singer and Nicholson in 1972. This model emphasizes that the lipids in the membrane allow for lateral movement of proteins, contributing to the membrane's fluidity.

5. **Conclusion**: The correct answer to the question is "Singer and Nicholson."

**Final Answer**: The fluid mosaic model of the cell membrane was first proposed by Singer and Nicholson.
