The centrosome is one of the organelles in the cells which have two centrioles inside of it. In contrast, a centriole is found in a cell, specifically inside centrosome, and it consists of microtubules. In terms of size, the size of a centrosome is double that of a centriole. A centrosome does not have a constant size because it can change at any time, particularly during cell division.
In contrast, a centriole is 500 nm long and 200 nm wide. Inside a centriole, there are three microtubules sets, and each set has three separate microtubules. In terms of formation, a centrosome is formed by the action of the pericentriolar material, which helps organize its content, i.e., the centrioles.
In contrast, a centriole is formed by different kinds of proteins, such as SPD-2, SAS-5, SAS-4, and SAS-6. Centrosomes are very important in the process of mitosis because they help control intracellular transport, whereas centrioles are a major part of this function.
