Solution

The correct option is C Assertion is correct but Reason is incorrect.
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, the correct answer is option C.
