Eventually, of course, this small daughter cell will grow in size and eventually will be the same size as this parent organism. Now, unicellular as well as multicellular organisms undergo the process of budding. One common example of a unicellular eukaryotic organism is the yeast cell, while an example of a multicellular organism that undergoes the process of budding is the hydra. Now, let's move on to the second type of asexual reproduction known as binary fission. So binary fission is the asexual reproduction that bacterial cells as well as other prokaryotic cells actually undergo. So what happens is inside the bacterial cell we have circular DNA, and the circular DNA basically begins to replicate itself.
