Which of the following best describes yeast?

Yeast is best described as a microscopic fungus. It belongs to a large group of organisms known as fungi, which includes mushrooms and molds. Yeasts are typically unicellular organisms that play a crucial role in fermentation, a process vital for baking and brewing. They convert sugars into alcohol and carbon dioxide, which helps bread to rise and imparts flavors in beverages like beer and wine. Understanding yeast as a fungus highlights its biological classification and distinguishes it from other types of microorganisms, such as bacteria or molds, which have different characteristics and uses.
