In Part 3 of this series on the Simple Cell, Things Just Don’t Float Around, we discussed the cytoskeleton of the cell. One of the structures mentioned was the centrosome, however it was never discussed in any detail. Today we are going to examine the centrosome.
There is a region of the cell that lies near the center and close to the nucleus. In this region there exists 2 barrel shaped structures called the centrioles. Each centriole is made up of nine bundles of three microtubules. This region of the cell contains not only the centrioles, but it also has a very thick and protein ladened mass of material known as the pericentriolar material. Altogether they make up the centrosome.
The centrosome and centriole have a number of functions within the cell and those functions are;
Tiny structures with huge functions, the centrioles and centrosomes are important structures within the cell. Yet I wonder how the first eukaryotic cells divided and replicated themselves before the centrioles and centrosomes evolved? Once again we see the impossibility of evolution and the magnificent handiwork of our Creator God.
