I was looking at the diagram of the eukaryotic cell and it shows the centrioles in the cytoplasm instead of the nucleus. Is this just an error? I thought that they were only in the nucleus or do they enter through the nuclear pores during mitosis?

Centrioles are not in the nucleus. They are located in cytoplasm..usually 90 degree to each other. During mitosis or mieosis, nucleor envelop breaks and centrioles travel to opposite poles and the spindles (microtubles) thats comes out of centrioles or MTOC (some kind of structure) connect to chromosomes at centromere and in Anaphase it pulls chromosomes apart.

In short, Centrioles ARE located in cytoplasm.

Side note, related to topic, centrioles are not necessary for cell division. But MTOC structure must be present. MTOC structure might include centrioles. I did not study MTOC structure in more detail. I don't think we need that for DAT.

I think what RCT is right, at least that's what I always thought.

Also know plants don't have centrioles.

Oh, centrioles are FA SHO in the cytoplasm. Usually they are not needed for cell division in animal cells BUT KNOW THE FOLLOWING FACT:

Centriols in spermatogenesis turn into the flagella of the sperm cell
