When an alga matures, it breaks up into two (or more) fragments. An alga reproduces by the asexual method of fragmentation. Many times we see slimy, green patches in ponds or in other stagnant water bodies such as lakes, etc. The green patches are due to the growth of plant-like organisms called algae. The breaking up of the body of the parent plant in two or more pieces on maturing, each of which subsequently grows to form a new plant, is called fragmentation. If this process continues, then a large number of yeast cells (or yeast plants) are produced in a short time Fragmentation The new yeast cells grow, mature and produce more yeast cells. After some time, all the yeast cells of the chain separate from one another and form individual yeast plants. The bud separates off from the parent yeast cell and forms a new yeast cell (or new yeast plant).The budding in yeast, however, often takes place so fast that the first buds start forming their own buds and all of them remain attached to the parent yeast cell forming a chain of yeast cells. The nucleus of parent yeast cell then divides into two parts and one part of the nucleus moves into the bud. In yeast, first a bud appears on the outside of the cell wall. Each single cell of yeast is a complete plant in itself. Yeast is a single-celled plant (or single-celled organism). Yeast is a non-green plant (which is a fungus). In budding, a small part of the body of the parent plant grows out as a bulb-like projection called bud which then detaches and becomes a new plant.
