Do fern fronds have sporangia?
Is my fern fertile? Spores are produced in structures called sporangia which are generally underneath the frond. These will not be on all fronds – try turning some over in summer to see what you can find.
May 28, 2023 · The sporophyte produces spores via a process called meiosis, which results in cells with half the number of chromosomes, or haploid cells (n). These haploid spores then grow into the gametophyte stage, which is small and often not readily recognizable.
Dec 28, 2020 · The diploid sporophyte produces haploid spores by meiosis, the same process that produces eggs and sperm in animals and flowering plants. Each spore grows into a photosynthetic prothallus (gametophyte) via mitosis .

The European woodmouse (Apodemus sylvaticus) has been found to eat the spores of Culcita macrocarpa, and the bullfinch (Pyrrhula murina) and the New Zealand lesser short-tailed bat (Mystacina tuberculata) also eat fern spores.
Mature sporophytes produce single-cell spores in sporangia (singular sporangium) aggregated into sori (singular sorus) on the undersides or at the ends of fronds. The spores are produced in enormous numbers, up to 10 billion each year on a large plant of Male Fern, and are dispersed by wind.
The sporangia is the structure which produces spores. In ferns, the sporangia are usually aggregated into particular bigger structures. If you turn over a fern frond and you might see lines, and those are aggregations of the sporangia.
Sep 19, 2024 · The fern spore—a single living cell, usually protected by a thick wall—is the main source of population dispersal, being readily carried by wind. Ferns display a wide diversity of spore types in terms of shape, wall structure, and sexuality, and these types prove to have great value in determining taxonomic relationships. The full ...
