Solution
The correct option is B Fluid nature of lipid and proteins The model given for the cell membrane is known as the Fluid mossaic model of the cell membrane. Cell membrane is fluid in nature.Due to the fluid nature of the cell,it can easily divide. Due to the fluid nature the cell is flexible and so it can grow in a systematic manner. It also helps in the process of endocytosis (phagocytosis and pinocytosis) due to its fluid nature. Intercellular junction is it forms in the junction between the different cellular part. Also it helps in secretion of different enzymes.
