The centriole is cylindrical and is made up of tubulin protein, and they are found in eukaryotic cells, and they are present in pairs. Both structures form the spindle fiber making complex called the centrosome. Centrioles are comprised of nine sets of microtubule triplets. They are placed in a tube, and in some species, doublets of these microtubules are also present.

Centrosomes are complex that have two centrioles. They are surrounded by pericentriolar material, which is a dense mass of protein. One of the repairs is the mother centriole, which forms the cilia and flagella. During cell division, centromere replicates only once, so the daughter cells have one centrome each.

The difference between centromere and centrioles is that centromeres are the whole complex containing a pair of centrioles and a dense mass of protein.

Centrosome and Centrioles are part of the cell that is required for cell division. Centrosomes are organelles. They comprise of two centrioles. These centrioles are located in chromosomes, and they are highly constricted. They are both made up of different things.

Centrosomes are made of tektin, microtubules, and centrin. Centrioles are made of centric heterochromatin. Both are located near the nucleus cells of animals and protist cells, but centrioles are also near the cell membrane.

Another difference between them is that they serve different functions. Centrosomes are apart of intracellular transport. Centrioles play a part in producing flagella and cilia.

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.
