Fungi need to produce so many spores because most spores simply die where they land, lacking water and food. Some fungal colonies can grow for a very long time and over a very large area. Genera like Selaginella and Salvinia which produce two kinds of spores macro and microspores are known as heterosporous. The megaspore and microspores germinate and give rise to female and male gametophytes, respectively. The female gametophytes in these plants are retained on the parent sporophyte for variable periods.Aspergillosis is an opportunistic infection that usually affects the lower respiratory tract and is caused by inhaling spores of the filamentous fungus Aspergillus, commonly present in the environment.The spores germinate and develop into hyphae, which enter blood vessels and, with invasive disease, cause hemorrhagic necrosis and infarction.PteridophytesPteridophytes are a group of vascular plants that reproduce via spores, rather than seeds.GametophyteThe gametophyte is the haploid, gamete-producing phase of the plant life cycle. In pteridophytes, the spores germinate to give rise to a multicellular, free-living photosynthetic gametophyte.ProthallusThe gametophyte in pteridophytes is called …Sporophytes produce haploid spores by meiosis. Spores germinate after dispersal to form the next generation of gametophytes. In species with chromosomal sex determination, male gametophytes possess an M chromosome and female gametophytes possess an F chromosome. In these species, sporophytes are obligate FM heterozygotes.The germination of dormant spores of Bacillus species is the first crucial step in the return of spores to vegetative growth, and is induced by nutrients and a variety of non-nutrient agents. Nutrient germinants bind to receptors in the spore's inner membrane and this interaction triggers the release of the spore core's huge depot of ...The spores travel from the mushroom along wind currents, and when they land in a moist place, they germinate. Each spore grows a network of fine threads of hyphae, which creep over and through the food. The hyphae release chemicals, which dissolve the food, and the digested nutrients are then absorbed by the growing fungus. ...Watch complete video answer for “The spores germinate to give rise to inconspicuous, small but” of Biology Class 12th.
