Question
Chapter 3.1, Problem 2CYU
Summary Introduction
To write:
The appearance of the plasma membrane under an electron microscope.
Introduction:
All the cells are enveloped by a flexible, thin, lipid bilayer known as the plasma membrane. It distinguishes the constituents of the cell from its surroundings. In order to conduct specialized and life-sustaining activities, each cell must possess the tendency to interchange substances across the plasma membrane.
