The correct option is (C) : Phospholipids form a bimolecular layer in middle part
Singer and Nicolson suggested a concept of the plasma membrane as a fluid mosaic. This hypothesis proposes that the plasma membrane is a bilayer of phospholipids that contains proteins, cholesterol, and carbohydrates, giving it a mosaic-like look. The hydrophilic and polar heads of the lipid molecules are placed on the outside of the phospholipid bilayer, while the hydrophobic and non-polar tails are positioned on the inside.

Cells are the basic building blocks of all living organisms. They can be classified into two main types: prokaryotic and eukaryotic.
Understanding the different types of cells is important for understanding their structure, function, and role in various biological processes.
