Nestled under fern leaves are tiny capsules chock-full of spores, tiny life vessels which, like seeds, are used for dispersal. Fern plants launch their spores with tiny catapults. Once in the air, wind and air currents can take the spores around the world.Click to see full answer. Keeping this in consideration, how do ferns reproduce by spores?These ferns lack true leaves and roots, but they spread by rhizomes and reproduce by spores that they produce on their leafless stems. After the sporangia eject the spores, the spores live underground where they grow into second-generation plants before maturing into aboveground whisk ferns.Additionally, what happens when a spore is released into the environment? Fungi release spores into the environment that are carried by air or water. Spores are highly resistant to environmental factors and can survive extremes of temperature and pH. This resistance is due partly to surface components, such as hydrophobic glycoproteins or lipoglycoproteins, that also help dissemination. Regarding this, why are spores on the underside of ferns? Individual spores are encased in structures called sporangia, which are the dots that appear on the underside of fern fronds. When the indusia burst open, they propel the spores forcefully from fern plants. If the spores land in an environment that favors their germination, they produce second-generation prothalli.How do Sporangia open?As the sporangium dries, evaporating water is drawn out from the cells of the annulus, causing the cells to shrink. The thick, inner cell walls don’t collapse, but the outer walls start to buckle. The process causes the curved surface of the annulus to shorten, thereby prying the sporangium open.
