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.
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.

A plantlet is a young or small plant, produced on the leaf margins or the aerial stems of another plant. [1] Many plants such as spider plants naturally create stolons with plantlets on the ends as a form of asexual reproduction. Vegetative propagules or clippings of mature plants may form plantlets. An example is mother of thousands. Many ...
It is a means of asexual propagation in plants. These structures are commonly found in fungi, algae, liverworts and mosses, but also in some flowering plants such as pygmy sundews and some species of butterworts. [1] [2] [page needed] Vascular plants have many other methods of asexual reproduction including bulbils and turions.
A few plants are pseudoviviparous – instead of reproducing with seeds, there are Monocots that can reproduce asexually by creating new plantlets in their spikelets. [8] Examples are seagrass species belonging to the genus Posidonia [9] and the alpine meadow-grass, Poa alpina. [10]
Tubers help plants perennate (survive winter or dry months), provide energy and nutrients, and are a means of asexual reproduction. [1] Stem tubers manifest as thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); examples include the potato and yam.
Normal asexual reproduction of plants, such as propagation from cuttings or leaves, has never been considered to be apomixis. In contrast to parthenocarpy , which involves seedless fruit formation without fertilization, apomictic fruits have viable seeds containing a proper embryo, with asexual origin.
