Are multicellular cells only found in eukaryotes

And no, procaryotes can not be multicellular, but that is not a rule, since scientists have been getting more and more evidence that procaryotic organisms can exist.

→ Note - there is no such thing as multicellular cells, but multicellular tissues/organisms.

Hope it helped,

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
