Is a fern frond a sporophyte?
The mature fern plant is the sporophyte structure that produces spores, which are released from sporangia.
What are the leaves in sporophyte ferns?
Generalized fern sporophyte. The spores are haploid; that is, they have one set of chromosomes. They are produced in specialized organs—the spore cases, or sporangia—on the fern leaves (fronds).
What is the sporophyte of a fern?
Plants we see as ferns or horsetails are the sporophyte generation. The sporophyte generally releases spores in the summer. Spores must land on a suitable surface, such as a moist protected area to germinate and grow into gametophytes.
Is the frond of a fern The sporophyte or the gametophyte?
sporophyte
While the sporophyte consisted of fronds and rhizomes, the gametophyte has leaflets and rhizoids. Within the gametophyte, sperm is produced within a structure called an antheridium.
What do fern spores look like?
Fern spores are the tiny, genetic bases for new plants. They are found contained in a casing, called sporangia, and grouped into bunches, called sori, on the underside of the leaves. Spores look like little dots and may be harvested for fern spore propagation by the intrepid gardener.
What are fronds on a fern?

Why are leaves of fern called fronds?
The leaf of a fern. These are called fronds to distinguish them from the leaves of flowering plants. Leaves in flowering plants are purely concerned with photosynthesis whereas fern fronds have both a photosynthetic function and a reproductive function. Each fern plant may have from one to many fronds.
What do fern fronds look like?
The fronds of many ferns begin as small, curled balls. As they grow, they change shape and start to look like the neck of a violin. That’s why they’re called fiddleheads. Many people think different tree ferns look the same, but if you look closely the various species are very different in size, shape and texture.
