Question

give three points of differences between the spores of aquatic fungi and terrestrial fungi​

Answer 1

Answer:

In terrestrial habitats, both a complete lack (desic- cation) and an excess of water (waterlogged soils, substrata) can inhibit fungal activity, though in the latter case, the decisive factor probably is lack of oxygen. Oxygen solubility in water is relatively low, and declines with temperature.

Answer 2

Answer:

• Aquatic fungi:

1. Fungus that dwell in marine or estuarine conditions are known as marine fungi. Despite not belonging to a taxonomic group, they do share a habitat. Obligate marine fungus must be completely or occasionally buried in sea water to thrive there.
2. In calcareous streams, spores of aquatic fungus involved in leaf decomposition are common. These are Ingoldian fungus, which are ascomycetes and a few basidiomycetes conidia.

• Terrestrial fungi​:

1. Terrestrial fungus belonging to the Zygomycota have a well-established, coenocytic, haploid mycelium. The hyphal cell wall of the thallus, which is haploid, contains a substantial amount of chitin and chitosan. In the zygomycetes, asexual reproduction produces sporangiospores, which are non-motile spores.
2. When a fungus's mycelium reaches a certain stage of development, it starts to produce spores either directly on the somatic hyphae or, more frequently, on special sporiferous (spore-producing) hyphae, which can be arranged loosely or grouped into complex structures called fruiting bodies or sporophores.
