The structure of the vegetative growth stage of fungi is called vegetative body. The vegetative bodies of most fungi are branched filaments, and a single filament is called mycelium. Many hyphae are collectively called mycelium. The hyphae growing on the substrate are called colonies. Microscopically, the mycelium is tubular, with cell walls and cytoplasm, colorless or colored.

Step 2 breed

When the vegetative life lasts for a certain period of time, fungi begin to transfer to the reproductive stage, forming various propagators, namely fruiting bodies. The propagules of fungi include asexual spores formed by asexual reproduction and sexual spores produced by sexual reproduction.

Extended data

The evolution of fungi:

1. Lifestyle: Aquatic fungi are primitive, and the evolution process is from aquatic to terrestrial. It is speculated that they may return to aquatic habits during the evolution process. Therefore, it is considered that the flagellated swimming spores are primitive and the immobile static spores are relatively evolved.

2. Nutrition: Saprophytic lifestyle is primitive lifestyle, and parasitic lifestyle is more advanced than saprophytic lifestyle. The obligate parasitic lifestyle is more advanced than the facultative parasitic lifestyle, and the highest lifestyle is the specific obligate parasitic lifestyle.

3. Fungal structure: from simple to complex, and then from complex to degradation, the special structure is lost, which simplifies the structure.
