Yeasts are classified as what type of organism?

Yeasts are classified as single-celled fungi, which distinguishes them from multicellular fungi such as molds and mushrooms. This classification highlights their structural simplicity; they typically consist of a single cell that can reproduce asexually through budding or fission. Yeasts are part of the larger kingdom of Fungi, which includes a variety of organisms that are used in food production, fermentation, and biotechnology.

Understanding the cellular structure is crucial in biology; yeasts possess eukaryotic cells, which means they have a defined nucleus and organelles, unlike prokaryotes, which lack these features. The other options mentioned do not accurately represent the classification of yeasts, reinforcing the idea that yeasts are unique among fungi due to their single-celled nature. This classification is fundamental in microbiology, as it influences how we study and apply knowledge about these organisms in various scientific and industrial contexts.
