Sorus is the cluster of "sporangia" (which are single-celled or many-celled structures in which spores are produced) and it is carried on the underside of a fern frond.
(A spore is a small, usually single-celled reproductive body that is capable of growing into a new organism).
The fern produces these as it's type of seeds, in order to reproduce and create new ferns. Spores are typical of the reproduction process in non-flowering plants, which is what a fern is.
