Spores are formed in the sporangiophore by encasing each haploid nucleus and cytoplasm in a tough outer membrane. During asexual reproduction, these spores are dispersed via wind and germinate into haploid hyphae. [4] Although sexual reproduction in fungi varies between phyla, for some fungi the sporangium plays an indirect role in sexual ...
For instance, the zygomycota use light as signal to promote vegetative reproduction and growth of aerial hyphae to facilitate spore dispersal. Fungal phototropism has been investigated in detail using the fruiting body, sporangiophore, of Phycomyces as a model. Phycomyces has a complex photoreceptor system. It is able to react to different ...
Hyphae that lack septa and are multi-nucleate; seen in Zygomycota and Oomycota. From Gr. kytos, cell. Distinct from a synctium, a multinucleate structure resulting from fusion of protoplasts. [69] colony A massed group of hyphae and spores of a single species, especially if all are grown from a single spore (e.g. in a lab). [70] columella. pl ...
They have few septa and lack clamp connections. Fusiform skeletal hyphae are the second form of skeletal hyphae. Unlike typical skeletal hyphae these are swollen centrally and often exceedingly broad, hence giving the hypha a fusiform shape. Binding hyphae are thick-walled and frequent branched. Often they resemble deer antlers or defoliated ...
Syzygites is a monotypic genus in Zygomycota.The sole described species is Syzygites megalocarpus, which was the first fungus for which sex was reported and the main homothallic representative in the research that allowed for the classification of fungi as homothallic or heterothallic.
The life stage at which a fungus lives, grows, and develops, gathering nutrients and energy.. The fungus uses this stage to proliferate itself through asexually created mitotic spores.
Science Fiction Literature through History: An Encyclopedia is a 2021 reference work written by science fiction scholar Gary Westfahl and published by ABC-Clio/Greenwood.The book contains eight essays on the history of science fiction, eleven thematic essays on how different topics relate to science fiction, and 250 entries on various science fiction subgenres, authors, works, and motifs.
While science fiction is a unique genre of fiction unto itself, it is also sometimes used as an umbrella term for a variety of distinct non-realistic or speculative fiction genres, most particularly fantasy. Conversely, speculative fiction is sometimes used as the umbrella term for SF, fantasy, Magic realism, horror, etc.
