Short fiberous rod-shaped organelles. Within the the cell, there are usually two centrioles collectivelt referred to as Diplosome . Located near the nucleas, each is made of 9 sets of 3 microtubules. Centrioles serve to organize micotubles and to determine polarity during late prophase and metaphase of cell division. These organelles can also move to a location below the cell membrane where they give rise to basal bodies, cilia, and flagellae.
Microtubules are straight or slightly curved delicate organelles located in almost all cells.
Microtubules serve several functions, they maintain cell shape as well as aiding in interacellular transport. In cellular division, they aid in pulling the chromosomes to different poles of the cell. It is also thought that microtubules could be responsible for transporting water within the cell. A wonderful informative page of microbiology.
