The noun YEAST has 2 senses: 1. a commercial leavening agent containing yeast cells; used to raise the dough in making bread and for fermenting beer or whiskey. 2. any of various single-celled fungi that reproduce asexually by budding or division. Familiarity information: YEAST used as a noun is rare. Dictionary entry details.
Yeast belongs to the fungi family. It is a very small single cell micro-organism. Like all other fungi it doesn't have the power to produce food by photosynthesis. Instead it ferments carbohydrates (sugars) to produce carbon dioxide and alcohol which gives bread it's texture, colour and aroma.
