At first glance, it seems that all fungus is macroscopic. There are, however, single-cell microscopic fungi.
Among these, we can mention the Saccharomyces cerevisiae. This fungus is used to make bread, cachaça, beer, etc., thanks to the fermentation that it performs.
Saccharomyces: unicellular fungi. Note that small shoots are new individuals being formed by asexual reproduction.
Multicellular fungi have a morphological characteristic that differentiates them from other living beings. Your body consists of two components: the fruiting body is responsible for the reproduction of the fungus through special reproductive cells, the spores, it's the mycelium consists of a web of filaments where each filament is called a hypha.
In most fungi, the cell wall is complex and consists of chitin, the same substance found in arthropod skeleton.
The energy reserve carbohydrate of most fungi is the glycogenjust like animals.
Depending on the fungal group, hyphae may have different types of organization. In cenocytic hyphae, present in simple fungi, the strand is continuous and the cytoplasm contains numerous nuclei inserted in it.
More complex fungi have septate hyphae, that is, there are dividing walls (septa) that separate the filament internally into more or less similar segments. In each septum there are pores that allow free movement of cytoplasmic material from one compartment to another.
Types of hyphae - Through the pores of the septate hyphae, cytoplasm and nuclei pass from one cell to another. In fungi, the nuclei are haploid.
