Anaerobic respiration is a form of energy production that the cell can do in the absence of oxygen. Both plants and animals are capable of doing this kind of respiration; however, there is a difference in the end products of each type of anaerobic respiration. This is where you can find the two points of difference between plant and animal anaerobic respiration.
In plants, anaerobic respiration gives off two products. The first product is alcohol, and that is why this process is also known as alcoholic fermentation. The other product is carbon dioxide gas. While not a plant, yeast is frequently used as an example of an organism that performs alcoholic fermentation. This is why yeast is used in the beer brewing and bread baking processes. It produces the alcohol in the beer (or wine), and the carbon dioxide is what causes the dough to rise. In animal cells, anaerobic respiration doesn't produce either of those two products. Instead, lactic acid is produced, and no carbon dioxide results from this process, which is also known as lactic acid fermentation. The lactic acid is what gives your muscles that familiar "burn" during or after a tough workout.
