Organelles which can be seen under electron microscope (highest magnification to more than 200,000x) are ribosomes, endoplasmic reticulum, lysosomes, centrioles, and Golgi bodies. A = 24mm. (ii) Presence of large central vacuole in plant cell. While many organelles of the cell have been discovered with the use of optical microscopes 19th century and the early 20th century, much smaller organelles ribosomes were first observed by the cell biologist George Emil Palade under the electron microscope in the mid-1950s in USA. Organelles that are attached to membrane and a true nucleus are not present in prokaryotic cells. 5mm = 24000mm. 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. The animal cell is more fluid or elastic or malleable in structure; the plant cell as more rigid and stiff walls.
