Plants reproduce sexually

opinion

Reproduction means producing offspring for the survival of the species. Plant reproduction is the production of new individuals or offspring in plantswhich can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion "Plants reproduce sexually" gametesresulting in offspring genetically different from the parent or Plants reproduce sexually. Asexual reproduction produces new individuals without the fusion of gametes, genetically identical to the parent plants and each other, except when mutations occur.

In seed plantsthe offspring can be packaged in a protective seedwhich is used as an agent of dispersal. Reproduction in which male and female gametes do not fuse, as they do in sexual reproduction.

Asexual reproduction may occur through buddingfragmentationfissionspore formation and vegetative propagation. Plants have two main types of asexual reproduction in which new plants Plants reproduce sexually produced that are genetically identical clones of the parent individual.

Vegetative reproduction invoves a vegetative piece of the original plant budding, tilleringetc. Apomixis occurs in many plant species and also in some Plants reproduce sexually organisms. Plants reproduce sexually apomixis and similar processes in non-plant organisms, see parthenogenesis. Natural vegetative reproduction is mostly a process found in herbaceous and woody perennial plants, and typically involves structural modifications of the stem or roots and in a few species leaves.

Most plant species that employ vegetative reproduction do so as a means to perennialize the plants, allowing them to survive from one season to the next and often facilitating their expansion in size. A plant that persists in a location through vegetative reproduction of individuals constitutes a clonal colony ; a single rametor apparent individual, of a clonal colony is genetically identical to all others in the same colony.

The distance that a plant can move during vegetative reproduction is limited, though some plants can produce ramets from branching rhizomes or stolons that cover a wide area, often in only a few growing seasons. In a sense, this process is not one of reproduction but one of survival and expansion of biomass of the individual. When an individual organism increases in size via cell multiplication and remains intact, the process is called vegetative growth.

However, in vegetative reproduction, the new plants that result are new Plants reproduce sexually in almost every respect except genetic. A major disadvantage to vegetative reproduction, is the transmission of pathogens from parent to offspring; it is uncommon for pathogens to be transmitted from the plant to its seeds in sexual reproduction or in apomixisthough there are occasions when it occurs.

Seeds generated by apomixis are a means of asexual reproduction, involving the formation and dispersal of seeds that do not originate from the fertilization of the embryos. Hawkweed Hieraciumdandelion Taraxacumsome Citrus Citrus and Kentucky blue grass Poa pratensis all use this form of asexual reproduction. Pseudogamy occurs in some plants that have apomictic seeds, where pollination is often needed to Plants reproduce sexually embryo growth, though the pollen contributes no genetic material to the developing offspring.
