Question

Which among the following is incorrect about fluid mosaic model?

(a) Plasma membrane was coined by Singer and Nicholson to be a fluid mosaic model

(b) According to this model, the proteins are dispersed randomly on the surface and the interior of the plasma membrane

(c) The word fluid in this model refers to the fluid flexible nature of the plasma membrane

(d) The model fails to explain the cell growth and cell division

This question was addressed to me in a national level competition.

My question is taken from Cell Basics topic in chapter Cell : The Unit of Life of Biology – Class 11

Answer 1

Right choice is (d) The model fails to explain the cell growth and cell division

To elaborate: Plasma membrane was coined by Singer and Nicholson to be a fluid mosaic model.  According to this model, the proteins are dispersed randomly on the surface and the interior of the plasma membrane. The word fluid in this model refers to the fluid flexible nature of the plasma membrane. The model explains the cell growth and cell division.
