Final answer:
Yeast in bread making represents both transformation and growth, as well as simplicity and tradition.
Step-by-step explanation:
In bread making, yeast represents both transformation and growth as well as simplicity and tradition.
The process of fermentation by yeast causes the bread dough to rise and gives it a light, aerated texture. This can be seen as a transformation and growth of the dough.
Furthermore, the use of yeast in bread making has a long tradition and is a simple and traditional way of leavening bread, as opposed to using chemical leavening agents like baking powder.
