Are Fungi Unicellular or Multicellular?

Answer: Microorganisms such as yeasts, moulds, and mushrooms are fungi, which are eukaryotic organisms. Fungi is the kingdom in which these species reside. Kingdom fungus creatures have a cell wall and are widely distributed.  In the world of living things, they are known as heterotrophs. Except for yeast, most fungi are multicellular creatures.

A fungus’ vegetative body can be unicellular or multicellular. Depending on the environment, dimorphic fungi can transition from a unicellular to a multicellular state. Yeasts are the common name for unicellular fungus. Candida species (a common fungal infection) and Saccharomyces cerevisiae (yeast) are examples of unicellular fungi.
