You must have seen bread getting spoiled after keeping for some days. Change in colour takes place because of development of bread mould which is a type of fungi.
Yeast is microscopic fungi which gets it's food from dead organic materials such as bread, grains etc. It is mostly used in fermenting alcohols and wines.
Yeast, converts starch in grain such as wheat, rice etc, to alcohol and releases carbon dioxide gas.
Let's learn about structure of Yeast in detail:
Since yeast is a unicellular, it's whole body is made of a single cell. It is oval in shape, where at one end vacuole and at the other end, nucleus is situated.
Cytoplasm is inner cell material which includes organelles like endoplasmic reticulum, ribosome, mitochondria.
Yeast is a type of fungi and thus it does not contain any chlorophyll which makes it incapable of performing photosynthesis.
