Yeast, which is used to make bread, belongs to the group :

Yeast is a unicellular microorganism that belongs to the group of fungi [2]. Specifically, the species used in bread making is Saccharomyces cerevisiae, commonly known as baker's yeast [1]. Unlike other fungi that are typically multicellular, such as moulds and mushrooms, yeast is primarily unicellular [3]. It is classified as a fungus because it is a eukaryotic organism with a cell wall made of chitin and lacks chloroplasts, meaning it cannot perform photosynthesis [3]. During the bread-making process, yeast respires and breaks down sugars, releasing carbon dioxide bubbles that cause the dough to rise and become fluffy [4]. While it shares some characteristics with protists, its genetic lineage and cell wall composition firmly place it within the Kingdom Fungi [3].
