Invention and evolution of the microscope
Since the invention of the first light microscope, microscopy has evolved so much. We are now able to see things at an atomic level. In this video, we will learn who invented the light microscope and the many other breakthroughs that...

Electron Microscopy (TEM and SEM)
We've talked a lot about light microscopy, but this technique has inherent limitations in resolution and magnification. The next paradigm in microscopy that emerged in the middle of the 20th century was electron microscopy. Because...

Vorticella sp. are often found in clusters, each stalk is individually attached to the surface. The stalk is made up of an external sheath that contains a fluid and a spirally arranged contractile fibril called a myoneme that contracts when stimulated.
When disturbed, the vorticella contracts and the stalk thread is shortened, causing the sheath to coil tightly like a spring.Phase Contrast illumination.
