This is a centriole.

Centrioles line up the chromosomes inside the cell and then they pull the chromosomes apart during cell replication. The function of centrioles is to help organize cell division.
- Plant cells lack centrioles entirely, and it is the mitotic spindle that lines up and pulls apart the chromosomes during mitosis. In experiments where centrioles are destroyed, spindle formation still occurs and functions normally.
It forms spindle fibers.
Centrioles are found in animal cells. They are just kind of all over the cytoplasm untill it is time to divide then they goto the ends.
