Let's have a look at another fascinating compartment of the cell, the centrosome! Located in close proximity to the nucleus, the centrosome is so small that it sometimes suffers from being overlooked. However, despite its humble size it is a very important organelle with great impact on cellular function.

The centrosome was first described in 1888 and has been a very popular organelle to study among biology researchers ever since (Conduit P.T. 2015). The most well characterized function of the centrosome is to serve as the organizing center for the microtubules that build up the internal architecture of the cell, the so-called cytoskeleton...Read more
