Study Notes
Size Scale of Biological Structures
- Various biological structures have different sizes, ranging from atoms to large cells and tissues.
- The image presents a scale from 100 μm down to 0.1 nm.
- 100 μm represents the typical size of most plant and animal cells.
- 10 μm represents the size of typical cell structures like the nucleus and the typical size of many bacteria
- 1 μm represents the size of mitochondria.
- 100 nm represents the size of the smallest bacteria and viruses.
- 10 nm represents the size of proteins and lipids
- 1 nm represents the size of small molecules.
- 0.1 nm represents the size of atoms.
- The image also shows the resolution limits of different types of microscopy.
- Light microscopy (L) can resolve structures down to 1 μm.
- Electron microscopy (EM), in particular super-resolution microscopy, can resolve structures significantly smaller than 1 μm.
- The image displays the different types of structures at various sizes.
- Different types of microorganisms such as bacteria are also present at various levels, from bacteria with 10 µm average size to smallest bacteria measured in 100 nm range.
- The illustration also displays cellular structures, such as mitochondria.
