Flowering plants, the dominant plant group, [9]: 168 reproduce both by sexual and asexual means. Their distinguishing feature is that their reproductive organs are contained in flowers. Sexual reproduction in flowering plants involves the production of separate male and female gametophytes that produce gametes.
Most common methods of natural vegetative reproduction involve the development of a new plant from specialized structures of a mature plant. In addition to adventitious roots , roots that arise from plant structures other than the root, such as stems or leaves, modified stems , leaves and roots play an important role in plants' ability to ...
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism.
Outcrossing, cross-fertilization or allogamy, in which offspring are formed by the fusion of the gametes of two different plants, is the most common mode of reproduction among higher plants. About 55% of higher plant species reproduce in this way. An additional 7% are partially cross-fertilizing and partially self-fertilizing (autogamy).

Morning glory vines spread their vegetation and flowers reproduce via mixed mating systems. Peanut plants utilize mixed mating systems, often with cleistogamous flowers. A mixed mating system (in plants), also known as “variable inbreeding” a characteristic of many hermaphroditic seed plants, where more than one means of mating is used. [1]
Multiple individuals have sprouted from turmeric rhizomes. Some monocots can reproduce asexually without the need for seeds. Clonal propagation is the production or division of vegetative structures which develop into new individuals that are genetically identical to their progenitor.
Both gametes the same (isogamy). Like other species of Cladophora, C. callicoma has flagellated gametes which are identical in appearance and ability to move. [20] Gametes of two distinct sizes (anisogamy). Both of similar motility. Species of Ulva, the sea lettuce, have gametes which all have two flagella and so are motile. However they are of ...
