Here's why:
* Bread mold belongs to the kingdom Fungi. Fungi are eukaryotes, meaning their cells have a nucleus.
* However, bread mold specifically belongs to the phylum Zygomycota. This phylum includes fungi that are not true eukaryotes and lack a membrane-bound nucleus.
So, while bread mold is a eukaryotic organism, its cells are somewhat unique in that they do not have a traditional nucleus.
