How is binary fusion different from budding?

Answer 1

Binary fission is a kind of asexual reproduction in which a single-celled organism splits into two identical single-celled organisms. The parent cell doesn't really exist separately any more, but it has been copied and split into two daughters.

Budding is a kind of asexual reproduction in which an organism grows a little mass of cells that develop into an offspring. The offspring may or may not separate from the parent, but the parent still exists. This happens in sponges and cnidarians. A yeast cell can bud, making a bulge on the side of the parent cell which develops into an independent cell that can break off and live on its own. The parent still exists.

Answer 2

Many unicellular organisms reproduce by binary fission; two identically sized daughter cells arise from a single mother cell. A classic example would be the e.coli bacterium. In some organisms, particularly many fungi, asexual reproduction is accomplished by forming a small bud on the side of the mother cell. The bud enlarges, pinches off, and detaches. It will grow to the size of the mother cell over time. A good example is the s. cerevisiae, or the brewer's yeast used in making beer(giving new meaning to the term "gimmie a bud").

Answer 3

Binary fission is a process that you see in some single celled animals (like ameba) as a form of asexual reproduction. In this process the organism will split into two identical organisms. Budding is seen in other organisms (can be seen in single celled animals and multi-celled animals such as sponges and anemones) where literally a piece of the organism forms a "bud" and breaks away to form a smaller complete replica of the organism.
