Yeast is a unicellular eukaryotic organism. It belongs to the kingdom Fungi. It is primarily used in baking, cooking and in alcohol industries as well. There are various strains of yeast and the most widely used one is <em>Saccharomyces cerevisiae</em>, also called the baker's or the brewer's yeast.
Scars on the yeast are actually the bud scars formed due to budding. Budding is the process by which the yeast reproduces and gives rise to its offspring. Hence every time a daughter bud pinches off from the yeast cell, a scar is formed.
