Answer:

The correct answer is- proteins embedded into two layers of phospholipids

Explanation:

The plasma membrane is a mosaic of many components like phospholipids, proteins, carbohydrates, and cholesterol. This mosaic nature of cell membrane gives a fluid character to the membrane.

So due to this fluidity, the proteins present in the membrane can do movements like flip flop which helps in the movement of molecules across the membrane.  

These proteins are called transporter which gives the property of selective permeability to the cell membrane because they bind specifically to some molecules and allow them to cross the cell membrane.

It is important that experimental information must be accumulated and arranged in a sequential fashion and in a form which can be understood by all: ideas may be more easily extracted, and results will be more easily drawn from data which have been arranged into a coherent pattern.
