In this process the multicellular organism breaks into two or more pieces on maturation. Hydra and planaria undergo regeneration.įragmentation occurs in multicellular organisms, be it plants or animals. Regeneration occurs in both plants and animals. These cells then move to their proper places to form organs and body parts. This happens because when the body of an organism that can undergo regeneration gets cut then the cells of cut body part divide rapidly and form a ball of cells. In this process, if the body of a parent organism gets cut, then each cut part can regenerate and form a whole new organism from its body parts. Regeneration is an asexual method of reproduction. Hydra reproducing by the method of budding. Hydra and yeast undergoes the process of budding. In the process of budding, a small bud grows on the body of parent organism and when the time comes it detaches itself to form a new organism. Plasmodium undergoes the process of multiple fission. When the favourable conditions come, the cyst breaks and the many daughter cells inside it are released. Inside this cyst the nucleus of an organism breaks in many smaller nuclei. This happens when cyst is formed around a unicellular organism. Multiple fission is also a process of asexual reproduction in which parent cell splits to form many new organisms. In this process, after splitting parent cell do not exist and two new organisms are formed.Įxamples of unicellular organisms that undergo binary fission are amoeba, paramecium, Leishmania etc. In binary fission, the parent cell divides into two after reaching a point where it has fully grown.
