1.	The first insights into the chemical nature of plasma membranes date back to __________(a) 1700(b) 1790(c) 1800(d) 1890This question was addressed to me in class test.My query is from Cellular Membranes in section Cellular Membranes of Cell Biology
Answer» The correct answer is (d) 1890 For explanation: The first insights into the chemical NATURE of cell membrane came from ERNST OVERTON of the University of Zürich during the 1890s. He stated that a substance entering the cell would first have to dissolve in the boundary layer of the cell.
