What does sporophyll mean?
A sporophyll is a specialized leaf or leaflike plant structure that bears sporangia, the small cases in which spores are produced. It is especially associated with ferns, whose leaves may be divided into fertile sections bearing spore-producing organs and sterile sections devoted mainly to photosynthesis. The term is useful in botanical description because it identifies the reproductive role of a leaf without implying that the structure is an ordinary foliage leaf. In some species, fertile and sterile leaves are plainly different in size or shape; in others, sporangia occur in strips or patches along an otherwise familiar-looking frond. The word comes from Greek roots meaning “spore” and “leaf,” reflecting the central function of this organ: producing and carrying the reproductive bodies of a spore-bearing plant.
nounA specialized leaf or leaflike plant structure that bears sporangia, the spore-producing cases found in ferns and certain other plants. In many ferns, fertile leaves or pinnae differ visibly from the sterile foliage.
- A leaf or leaflike plant organ on which sporangia are borne, especially in ferns.
"Each fertile sporophyll carries rows of sporangia along its underside."
"The underside of the sporophyll is lined with clusters of sporangia."
"In this species, fertile sporophylls are sharply distinguished from the broad sterile fronds."
The standard plural used in botanical descriptions.
"Several fertile sporophylls were arranged along the axis of the frond."
A sporophyll is essentially a leaf redesigned to package and release spores rather than seeds.

Where does sporophyll come from?
The word was formed in the 19th century from Greek spora, meaning “seed” or “spore,” and phyllon, meaning “leaf.” The combined form was adopted in botanical terminology to designate a leaflike structure that bears sporangia. Its elements are reflected in related English words such as spore, sporangium, and the combining form phyll-.

How sporophyll is actually used
This is a specialized botanical term. It is most often used in descriptions of ferns and other vascular plants that produce spores rather than seeds.
