Yeast is a leavening agent. Yeast releases CO2 as a waste product. Bread dough has protein structures called Gluten. The CO2 from the yeast gets trapped in pockets between the gluten strands, thus causing the dough to rise. When the bread bakes, the yeast continues to reproduce and create CO2 gas. The yeast eventually dies when the temperature of the dough gets hot enough. Without yeast, bread would be flat and tough.
