Question

Assertion: A cell membrane shows
fluid behaviour.
Reason: A membrane is a mosaic or
composite of diverse lipids and
proteins.
(Both are correct or not )

Answer 1

Plasma membrane is the outer covering of all cells but it is present below the cell wall in plant cells. It is composed of phospholipid bilayer structure with embedded proteins and gives the mosaic-like appearance. The lipid molecules give fluidity and elasticity to the membrane and membrane protein gives semi permeability to the membrane. Thus, both assertion and reason are correct
