Since sexual reproduction is often more narrowly defined as the fusion of gametes (fertilization), spore formation in plant sporophytes and algae might be considered a form of asexual reproduction (agamogenesis) despite being the result of meiosis and undergoing a reduction in ploidy. However, both events (spore formation and fertilization) are ...
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. [1] [2] [3]
Plant breeders use different methods depending on the mode of reproduction of crops, which include: Self-fertilization, where pollen from a plant will fertilise reproductive cells or ovules of the same plant; Cross-pollination, where pollen from one plant can only fertilize a different plant
Apomixis is asexual reproduction through seeds and does not require pollination. It is distributed throughout the monocot clade in Poales, Asparagales, Liliales, Dioscoreales, and Alismatales. Thus apomixis may have evolved once in a basal ancestor and has since repeatedly become lost. [17]
When propagating plants to increase a stock of a cultivar, thus seeking identical copies of parent plant, various cloning techniques (asexual reproduction) are used. Offsets are a natural means by which plants may be cloned. In contrast, when propagating plants to create new cultivars, sexual reproduction through pollination is used to create ...
Some liverworts are capable of asexual reproduction; in bryophytes in general "it would almost be true to say that vegetative reproduction is the rule and not the exception." [25] For example, in Riccia, when the older parts of the forked thalli die, the younger tips become separate individuals. [25]
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 ...
