WORLDMOSQUES

A mosque : A place of worship for followers of Islam. Muslims often refer to the mosque by its Arabic name, masjid, Arabic: مسجد‎ — pronounced [ˈmæsʤɪd] (pl. masājid, Arabic: مساجد‎ — /mæˈsæːʤɪd/). The word "mosque" in English refers to all types of buildings dedicated for Islamic worship, although there is a distinction in Arabic between the smaller, privately owned mosque and the larger, "collective" mosque (Arabic: جامع‎, masjid jāmiʕ), which has more community and social amenities.
The primary purpose of the mosque is to serve as a place where Muslims can come together for prayer and some other activities of their life (i.e, a centre for information, education, and dispute settlement). The Imam leads the prayer. Nevertheless, mosques are known around the world nowadays for their general importance to the Muslim community as well as their demonstration of Islamic architecture. They have developed significantly from the open-air spaces that were the Quba Mosque and Masjid al-Nabawi in the seventh century. Today, many mosques have elaborate domes, minarets, and prayer halls. Mosques originated on the Arabian Peninsula, but are now found in all inhabited continents. They are not only places for worship and prayer, but also places to learn about Islam and meet fellow believers

FLOWERS

A 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.
In addition to serving as the reproductive organs of flowering plants, flowers have long been admired and used by humans, mainly to beautify their environment but also as a source of food.
Flower specialization and pollination A poster with twelve species of flowers or clusters of flowers of different familiesEach flower has a specific design which best encourages the transfer of its pollen. Cleistogamous flowers are self pollinated, after which, they may or may not open. Many Viola and some Salvia species are known to have these types of flowers.
Entomophilous flowers attract and use insects, bats, birds or other animals to transfer pollen from one flower to the next. Flowers commonly have glands called nectaries on their various parts that attract these animals. Some flowers have patterns, called nectar guides, that show pollinators where to look for nectar. Flowers also attract pollinators by scent and color. Still other flowers use mimicry to attract pollinators. Some species of orchids, for example, produce flowers resembling female bees in color, shape, and scent. Flowers are also specialized in shape and have an arrangement of the stamens that ensures that pollen grains are transferred to the bodies of the pollinator when it lands in search of its attractant (such as nectar, pollen, or a mate). In pursuing this attractant from many flowers of the same species, the pollinator transfers pollen to the stigmas—arranged with equally pointed precision—of all of the flowers it visits.
Anemophilous flowers use the wind to move pollen from one flower to the next, examples include the grasses, Birch trees, Ragweed and Maples. They have no need to attract pollinators and therefore tend not to be "showy" flowers. Male and female reproductive organs are generally found in separate flowers, the male flowers having a number of long filaments terminating in exposed stamens, and the female flowers having long, feather-like stigmas. Whereas the pollen of entomophilous flowers tends to be large-grained, sticky, and rich in protein (another "reward" for pollinators), anemophilous flower pollen is usually small-grained, very light, and of little nutritional value to insects.
