NEET Biology: Biology - Cell Structure questions with solutions

Q1. What is true of fluid mosaic model?

1. Phospholipid monolayer is present over protein layer
2. Phospholipid bilayer is present over protein layer
3. Protein embedded in phospholipid bilayer
4. Phospholipid layer is sandwitched between two protein layers.

Answer: Protein embedded in phospholipid bilayer

The fluid mosaic model describes a membrane made of a phospholipid bilayer that is fluid and contains proteins scattered or embedded within it. This arrangement creates a mosaic-like pattern of different components moving laterally in the membrane.
