flower:-, also known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to mediate the union of male sperm with female ovum in order to produce seeds. The process begins with pollination, is followed by fertilization, leading to the formation and dispersal of the seeds. For the higher plants, seeds are the next generation, and serve as the primary means by which individuals of a species are dispersed across the landscape. The grouping of flowers on a plant are called the inflorescence.
POLLINATION:-The primary purpose of a flower is reproduction. Flowers are the reproductive organs and mediate the joining of the sperm contained within pollen to the ovules, normally from one plant to another but many plants also can pollinate their own flowers. The fertilized ovules produce seeds that are the next generation. Sexual reproduction produces genetically unique offspring, allowing for adaptation. Flowers have specific designs which encourages the transfer of pollen from one plant to another of the same species. Many plants are dependent upon external factors to move pollen between flowers, including the wind and animals, especially insects. Even large animals such as birds, bats, and pygmy possums can be employed. The period of time during which this process can take place (the flower is fully expanded and functional) is called anthesis.
FERTILISATION AND DISPERSAL:-Some flowers with both stamens and a pistil are capable of self-fertilization, which does increase the chance of producing seeds but limits genetic variation. The extreme case of self-fertilization occurs in flowers that always self-fertilize, such as many dandelions. Conversely, many species of plants have ways of preventing self-fertilization. Unisexual male and female flowers on the same plant may not appear or mature at the same time, or pollen from the same plant may be incapable of fertilizing its ovules. The latter flower types, which have chemical barriers to their own pollen, are referred to as self-sterile or self-incompatible (see also: Plant sexuality

The genus Lilium are herbaceous flowering plants normally growing from bulbs. They comprise a genus of about 110 species in the lily family, Liliaceae. They are important as large showy flowering garden plants. They are important culturally and in literature in much of the world.
Some species are sometimes grown or harvested for the edible bulbs.
The species in this genus are the true lilies. Many other plants exist with "lily" in the common English name, some of which are quite unrelated to the true lilies
Range:-
The range of liles in the Old World extends across much of Europe, the north Mediterranean region, across most of Asia to Japan, south to the Nilgiri mountains in India, and south to the Philippines. In the New World they extend from southern Canada through much of the United States.
They are commonly adapted to either woodland habitats, often montane, or sometimes to grassland habitats. A few can survive in marshland and a single one is known to live as an epiphyte (L. arboricola). In general they prefer moderately acidic or lime-free soils
Jasmine:- or Jessamine ,Jasminum from Persian yasmin, i.e. "gift from God"[4][5], via Arabic[6]) is a genus of shrubs and vines in the olive family (Oleaceae),with about 200 species, native to tropical and warm temperate regions of the Old World. The majority of species grow as climbers on other plants or on structures such as chicken wire, gates or fences. The leaves can be either evergreen (green all year round) or deciduous (falling leaves in autumn), and are opposite in most species; leaf shape is simple, trifoliate or pinnate with up to nine leaflets.
Description:-:
Jasmine flowers are generally white, although some species have yellow flowers. Unlike most genera in the Oleaceae which have four corolla lobes ("petals"), jasmines often have five or six lobes. They are often strongly and sweetly scented. Flowering is in spring or summer in most species, but in a few species, notably J. nudiflorum, in winter on the bare branches of this deciduous species.
Cultural importance and other information:-
The Jasmine is the National Flower of the following countries:
The Philippines, where it is known as "Sampaguita", and is usually strung on garlands which are then used to adorn religious images.
Indonesia, where the variety Jasminum sambac is the "puspa bangsa" (National Flower), and goes by the name "Melati", In the country, especially the island of Java, it is the most important flower in wedding ceremonies for ethnic Indonesians.
Pakistan, where Jasminum officinale is known as the "Chambeli" or "Yasmine" is the national flower.
