Which classification includes organisms such as yeast and molds?

The classification that includes organisms such as yeast and molds is Fungi. Organisms in this group share specific characteristics that define them as fungi, which are distinct from other kingdoms. Fungi are eukaryotic, meaning their cells contain a nucleus and other organelles. They are primarily heterotrophic, absorbing nutrients from their environment through external digestion, which sets them apart from plants that are autotropic and produce their food through photosynthesis.

Yeasts are unicellular fungi that reproduce by budding, and they play important roles in processes like fermentation. Molds, on the other hand, are typically filamentous fungi that grow in a network of hyphae. Together, they illustrate the diverse forms that fungi can take and their significant roles in ecosystems as decomposers, as well as their applications in food production and medicine.

The other classifications mentioned do not include these organisms; for instance, Animalia consists of multicellular, heterotrophic animals, Monera includes prokaryotic organisms like bacteria, and Protozoa consists of mainly unicellular eukaryotes that are typically motile. Therefore, Fungi is the only classification that accurately encompasses yeast and molds.
