sori
In ferns, a sorus is a cluster of sporangia on the edge or underside of a fertile frond.
sori
Ferns that have groups of sporangia called sori. Sori are clusters of sporangia found on the undersides of fern fronds where spores are produced. These structures help facilitate the dispersal of spores for reproduction in ferns.

The correct term for a fern 'leaf' is a frond although "leaf" is perfectly acceptable.
The word "sori" is the plural form of "sorus." According to Wikipedia, the free encyclopedia, "In ferns, a sorus (pl. sori) is a cluster of sporangia on the edge or underside of a fertile frond. In many species, they are protected by an umbrella-like cover called the indusium."Source: http://en.wikipedia.org/wiki/Sori
There is typically one sorus per leaflet on a fern. The sorus is a cluster of sporangia where spores are produced for reproduction.
Clusters of sporangia are structures found on the underside of fern fronds where spores are produced and released for reproduction. Each sporangium contains spore-producing cells that undergo meiosis to produce haploid spores.
Fern prothallia are small heart-shaped structures that produce reproductive structures called sporangia. Sporangia are responsible for producing spores in ferns, which can develop into new fern plants.
the leaf of a fern plant
The leaf of a fern is called a frond. A young frond is referred to as a fiddlehead. When young fronds come up from the ground, they're tightly coiled.
