Understanding the Differences Between Bacteria and Fungi

Bacteria come from a different kingdom of life, tend to be single-celled organisms with minimal internal organization, and do not form large networks. On the other hand, fungi, like plants and animals, have complex internal organization with different sub-organelles and tend to be network structures. Yeast, which makes up 10% of the fungal world, does not form extensive networks like other fungi, and instead, some yeasts behave similar to bacteria by dividing through budding. There are numerous strains of yeast, with commercial products typically using a handful of strains of brewers or baker's yeast out of the wide variety available.
