About this image

Scanning electron micrograph of two yeast cells in the process of budding. The larger cells are about 4 micrometres in diameter. Yeasts are single-celled organisms that reproduce asexually. Those that do so by budding, growth from an offshoot of a parent cell rather than by splitting into equal-sized offspring, come into the order Saccharomycetales or true yeasts. These are the yeasts used in baking and in fermenting. In total there are over 1500 species of yeasts in two phyla, the Ascomycota and the Basidiomycota. VIB Bio-imaging Core, Gent, Belgium
