Organelle - Wikipedia, the free encyclopedia (457 words) |
 | Organelles were historically identified through the use of microscopy, and were also identified through the use of cell fractionation. |
| The larger organelles, such as the nucleus and vacuoles, are easily visible with moderate magnification (although sometimes a clear view requires the application of chemicals that selectively stain parts of the cells); they were among the first biological discoveries made after the invention of the microscope. |
| Organelles which have double-membranes and their own DNA are believed by many biologists of having originally come from incompletely consumed or invading prokaryotic cells, which were adopted as a part of the invaded cell through endosymbiosis. |
