Edexcel Ial Biology. The scientist who first discovered cell is Robert Hooke. etc.) The Plant Cell back to menu or next or previous . 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. How its different from animal cell? Plant Cell And Animal Cell Under Electron Micrograph . Three layers together measure approximately 75 Å in thickness. The electron microscope Electron microscopes use a beam of electrons instead of beams or rays of light. Red blood cells (erythrocytes) are biconcave, disc-shaped cells that transport oxygen from the lungs to body cells. Cell Wall and Cell Membrane a.
