What do fungi include?

Fungi are a distinct group of organisms that play crucial roles in ecosystems and can be identified by their characteristics. One of the defining features of fungi is that they include microscopic plant parasites such as molds and yeasts. Molds are fungi that grow in multicellular structures, while yeasts are single-celled fungi that are often involved in fermentation processes. Both types can reproduce through spores and can be found in various environments, contributing to decomposition and nutrient cycling.

Molds can cause spoilage in food and contribute to foodborne illness,while beneficial yeasts are used in baking and brewing. This connection to both harmful and beneficial fungi highlights their dual role in various contexts, reinforcing the significance of option A as the correct choice.
