Electron Microscopic Study of Cell and Organelles: The invention of electron microscope and its subsequent use for scientific work has made it possible to have much clear and detailed picture of cell and organelles. For the purpose of electron microscopic study of cell and organelles, consider the electron micrograph shown by schematic diagram in the fig. Under the electron microscope, the cell membrane is seen to be formed of three layers- a white layer, formed of liquid molecules, is sandwiched between two dark layers, formed of protein molecules. Three layers together measure approximately 75 Å in thickness. In plant cells, the … Continue reading Electron Microscopic Study of Cell and Organelles
