Why bread dough rises?
The yeast cells in bread dough ferment sugars and produce gas (carbon dioxide). This makes the dough rise.

Why do you need yeast for yeast bread?
You don't need yeast to make bread, but the result is unleavened bread. Yeast is a form of bacteria that produces CO2 bubbles in the dough as it consumes sugars. This makes the bread dough rise and the resultant baked bread is lighter and fluffier - leavened bread.

How do the microbes in bread work?
Bread is not "formed" by microorganisms. However, yeast is added to bread dough as leavening. The yeast, consisting of many billions of microorganism, consume and digest sugars in the dough which produces gas. The gas bubbles cause the bread dough to expand or "rise."
What does yeast use to make bread dough rise?
Yeast turns some of the sugar in bread dough into alcohol and carbon dioxide. The carbon dioxide fills the bread with a lot of little bubbles. That makes it easy to eat. Without yeast bread would be like eating raw spaghetti.
What is in the bread dough that yeast feeds on?
It feeds on sugar
What causes bread and pizza dough to rise?
Yeast.
Why is yeast added to bread dough and the dough covered with a cloth and set aside a few hours after baking?
The yeast feeds on carbohydrates in the dough and produces Carbon dioxide gas, this is what causes all the little bubbles that are present in bread and what causes it to "rise." It is left for a while in order for this process to happen and is usually allowed to double in size. Bread with no yeast in it is called "unleaven Bread."
Why does bread rise when yeast is added?
Yeast is added to bread along with moisture and sugar, and the dough is kept in a moist, warm environment. During this rising time, the yeast consumes the sugar in the dough and release CO2 gas, which is trapped in the dough and causes the dough to rise. When the dough is baked, the yeast is killed, but the bubbles created by the gas remain.
