this is sexual reproduction of seed is called apomixis .a diploid cell in the ovule give rise to the embryo and the ovule mature into seed . which in the dendeline are disappeared by windblown fruite
Apomixis is a type of asexual reproduction in which seeds are produced without fertilization. It allows for the formation of genetically identical offspring to the parent plant. This process can be advantageous for plant breeding and propagation as it maintains desirable traits.
Generally, apomixis is reproduction in plant life without fertilization.The correct spelling is parthenogenesis and generally refers to human conception without fertilization by a man.
One advantage of apomixis is that it allows for the production of offspring that are genetically identical to the parent plant, preserving desirable traits in a population. This can be useful in agriculture and horticulture for maintaining specific characteristics in crops or ornamental plants.
Apomixis is the mechanism of seed production without involving the process of meiosis and syngamy. It plays an important role in hybrid seed production. The method of producing hybrid seeds by cultivation is very expensive for farmers. Also, by sowing hybrid seeds, it is difficult to maintain hybrid characters as characters segregate during meiosis. Apomixis prevents the loss of specific characters in the hybrid. Also, it is a cost-effective method for producing seeds.

Nucellar embryony (notated Nu+) is a form of seedreproduction that occurs in certain plant species, including many citrusvarieties. During the development of seeds from plants that possess this genetic trait, the nucellar tissue which surrounds the megagametophyte can produce additional embryos (polyembryony) which are genetically identical to the parent plant. These nucellar seedlings are essentially clonesof the parent. By contrast, zygoticseedlings are sexually produced and inherit genetic materialfrom both parents. Zygotic and nucellar embryos can occur in the same seed, and a zygotic embryo can divide to produce multiple embryos.In botany, apomixis was defined by Hans Winkler as replacement of the normal sexual reproduction by asexual reproduction, without fertilization.[ 1] This definition notably does not mention meiosis. Thus "normal asexual reproduction" of plants, such as propagation from cuttings or leaves, has never been considered to be apomixis, but replacement of the seed by a plantlet, or replacement of the flower by bulbils are types of apomixis. Apomictically produced offspring are genetically identical to the parent plant.
The kind of growth which involves roots and shoots but not the reproductive structers which occurs in most plants is known as apomixis.
Parthenocarpy is the process by which a fruit develops without fertilisation. As a result the fruit is seedless. Apomixis is the process by which seeds develop without fertilisation. this takes place when the megaspore mother cell does not undergo meiosis or a cell from the nucellus develops into the embryo.

Haploid cells in plants called "haploid cells" or "gametophytes" have the ability to develop into a whole plant without fertilization. This process is known as "apomixis" and allows for asexual reproduction in certain plant species.

Seeds can develop without fertilization through apomixis, where the embryo is formed without meiosis or fertilization, producing a genetic clone of the parent plant. Another way is through parthenocarpy, where a fruit develops without fertilization, but the seeds within it are not viable.
