Centrioles and centrosomes, unique to animal cells, organize spindle fibers, with a centrosome comprising two perpendicularly oriented centrioles, each containing nine microtubule triplets.
Centrioles and centrosomes, found only in animal cells, organize spindle fibers; a centrosome contains two centrioles arranged perpendicularly, each housing nine triplets of microtubules.
| Front | Centrioles/Centrosomes |
|---|---|
| Back | - only animals - organize spindle fibers - (plants have microtubule organizing regions instead) - 2 centrioles intersect at a right angle, forming 1 centrosome - inside 1 centriole: 9 triplets of microtubules |
