Which type of fungi is not multicellular?

Yeasts are classified as unicellular fungi, making them distinct from the other types of fungi mentioned. Unlike Ascomycetes, Basidiomycetes, and molds, which can form complex multicellular structures, yeast cells typically exist as single-celled organisms. They reproduce asexually through budding or fission and are commonly found in environments rich in sugars, such as in fruit or as part of fermentation processes.

Yeasts belong to the group of fungi that can carry out fermentation, and they play crucial roles in baking, brewing, and the production of various foods. This unicellular nature allows them to adapt quickly to different environments, contributing to their widespread presence in nature. In contrast, Ascomycetes, Basidiomycetes, and molds can form mycelial networks, which consist of multicellular filaments called hyphae, leading to different morphological and ecological characteristics.
