Text Solution

Verified by Experts

The correct Answer is:
A
The fluid mosaic model was put forward in 1970 by SJ singer and GL nicholson, According to this model, plasma membrane is composed of phospholipids, extrinsic proteins (peripheral proteins) and intrinsic proteins (integral proteins). The plasma membrane is highly fluidic due to the movement of phospholipids and proteins present in it.
