Smallest cell structure by light microscope
Webb27 feb. 2015 · This cryo-electron tomography image reveals the internal structure of an ultra-small bacteria cell like never before. The cell has a very dense interior compartment and a complex cell wall. The darker spots at each end of the cell are most likely ribosomes. The image was obtained from a 3-D reconstruction. The scale bar is 100 nanometers. WebbThe smallest thing seen with the naked eye is about 0.05 mm. For all cells we need a microscope to see them in any detail. The best unit to measure most cells is the micrometre, symbol μm....
