The asexual reproduction predominant which Depends upon the involvement of the entire thallus or a part of it, the fungi can be holocarpic or eucarpic. In fact, fungi are one of the only organisms that are able to break down tough plant structural compounds such as lignin, tannins, and cellulose, and as such play a crucial role in aquatic plant matter decomposition. Solved Examples for You. They are mostly aquatic, and their gametes are the only fungal cells known to have flagella. Aquatic hyphomycetes (also known as freshwater hyphomycetes, amphibious fungi or Ingoldian fungi) are a polyphyletic group of true fungi (Bärlocher, 1992a; Belliveau & Bärlocher, 2005). Zygomycota (conjugated fungi) produce non-septated hyphae with many nuclei. Their taxonomy and identification have traditionally been based on the morphology and development of asexually produced spores (mitospores or conidia). Holocarpic fungi Fungi Another decomposer found underwater and on land, fungi vary in size from being a small microdecomposer to certain mushrooms that grow bigger than small mammals. The spores of many terrestrial fungi are carried into water by rain, and so may be isolated by conventional mycological techniques. These spores are conidia. Question: Write a note on Deuteromycetes. For Amphibious fungi they live in streams. They come in all shapes and sizes. They reproduce both sexually and asexually; the asexual spores are called zoospores. Some members are saprophytes or parasites. Recent studies showed that some fungi are able to degrade herbicides, insecticides ( Oliveira et al., 2015 ) … Examples include penicillin, lovastatin, and cyclosporine. When underwater, fungi are typically microscopic, though once they begin decomposing a plant or an animal, they grow a thick, visible gelatinous layer around the organic matter. The Deuteromycetes reproduce only by asexual spores. There is a bounty of fungi around these waters. Answer: They are imperfect fungi because we only know about the asexual or vegetative phases of these fungi. Examples: Alternaria, Helminthosporium, Collectotrichum, Trichodenna etc. Yet others may have a transient aquatic existence, possibly brought on a substratum by wind or swept by floods into water. These fungi are aquatic ascomycetes. They include Amphibious fungi and Aero-aquatic. The fungi then use the resulting simple sugars and amino acids to grow. Zygomycota (conjugated fungi) have a multicellular body structure; features include zygospores and presence in soil; examples … It is therefore necessary to define carefully the term aquatic fungus. Chytridiomycota (chytrids) are considered the most primitive group of fungi. For example, aquatic fungi can sequester greater amounts of heavy metals than bacteria (Massaccesi et al., 2002), and outweigh bacteria in biomass (Findlay and Arsuffi, 1989). These organisms differ radically, and share only their small size; most are not visible without a microscope, though colonies of some can be seen with the naked eye. Chytridiomycota (Chytrids) may have a unicellular or multicellular body structure; some are aquatic with motile spores with flagella; an example is the Allomyces. In these two types there are smaller groups that are developed in different habitats. Aquatic Organisms: Microorganisms Microorganisms include members of the plant kingdom, protozoa, bacteria, and fungi. Fungi reproduced by vegetative, asexual, and sexual means. Through this, they help prevent the buildup of nutrients in your pond, thus promoting healthy water quality. Lentinan and eritadenine may be helpful as well. Some chemicals found in fungi are used as medicines when formulated correctly. Reproduction of Fungi. Aquatic Fungi. Penetrating their substrates, aquatic ascomycetes release enzymes that break down the ligno-cellulose of plant cell walls, the pectins that hold cells together, and starch stored in plant tissues.
