Per NCERT, what is the FLUID MOSAIC model of the cell membrane?
AA single rigid sheet of protein with no lipids
BA lipid BILAYER (two layers of fat molecules with water-loving heads outwards + water-repelling tails inwards) with proteins embedded that can move sideways like 'tiles in a mosaic'
CA continuous tube of pure water
DA solid block of fat with no fluidity
Answer & Solution
Correct answer: B. A lipid BILAYER (two layers of fat molecules with water-loving heads outwards + water-repelling tails inwards) with proteins embedded that can move sideways like 'tiles in a mosaic'
Per NCERT §2.2.1 Fig 2.7, the fluid mosaic model = lipid bilayer + mobile embedded proteins. The other options misstate.
