Fragmentation is seen in many organisms. Animals that reproduce asexually include planarians, many annelid worms including polychaetes [17] and some oligochaetes, [17] turbellarians and sea stars. Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation, such as gemmae in mosses and ...
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes , resulting in offspring genetically different from either parent.
The Komodo dragon, which normally reproduces sexually, has also been found able to reproduce asexually by parthenogenesis. [54] A case has been documented of a Komodo dragon reproducing via sexual reproduction after a known parthenogenetic event, [ 55 ] highlighting that these cases of parthenogenesis are reproductive accidents, rather than ...
Obligate parthenogenesis is the process in which organisms exclusively reproduce through asexual means. [39] Many species have transitioned to obligate parthenogenesis over evolutionary time. Well documented transitions to obligate parthenogenesis have been found in numerous metazoan taxa, albeit through highly diverse mechanisms.
Some cacti and other plants have jointed stems. When a stem segment, called a pad, falls off, it can root and form a new plant. Leaves of some plants readily root when they fall off, e.g. Sedum and Echeveria. Fragmentation is observed in nonvascular plants as well, for example, in liverworts and mosses. Small pieces of moss "stems" or "leaves ...
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
