An alga which reproduces by the asexual reproduction method called fragmentation is :
Two very small organisms X and Y both reproduce by the method of budding. Organism X is industrially very important because it is used in making alcohol from sugar. It is also used in making bread. Organism Y Lives in freshwater. If organism Y gets cut into a number of parts accidently, each cut part can grow to form complete organism.
