The function of a flower is to mediate the union of male and female gametes. The process is termed pollination. Many flowers are dependent upon the wind to move pollen between flowers of the same species. Others rely on animals (especially insects) to accomplish this feat. The period of time during which this process can take place (the flower is fully expanded and functional) is called anthesis.
Many flowers in nature have evolved to attract animals to pollinate the flower, the movements of the pollinating agent contributing to the opportunity for genetic recombinations within a dispersed plant population. Flowers that are insect-pollinated are called entomophilous (literally "insect-loving"). Flowers commonly have glands called nectaries on their various parts that attract these animals. Birds and bees are common pollinators: both having color vision, thus opting for "colorful" flowers. Some flowers have patterns, called nectar guides, that show pollinators where to look for nectar; they may be visible to us or only under ultraviolet light, which is visible to bees and some other insects. Flowers also attract pollinators by scent. Many of their scents are pleasant to our sense of smell, but not all. Some plants, such as Rafflesia, the titan arum, and the North American pawpaw (Asimina triloba), are pollinated by flies, so produce a scent imitating rotting meat.
In any case, pollinators are attracted to the plant, perhaps in search of nectar, which they eat. The arrangement of the stamens ensures that pollen grains are transferred to the bodies of the pollinator. In gathering nectar from many flowers of the same species, the pollinator transfers pollen between all of the flowers it visits.
The flowers of other species are pollinated by the wind (for example, grasses); they have no need to attract pollinators and therefore tend not to be "showy". Wind-pollinated flowers are referred to as anemophilous. 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, though it may still be gathered in times of dearth. Honeybees and bumblebees actively gather anemophilous corn (maize) pollen, though it is of little value to them.

It all depends on what sort of pollinator they're cooperating with. Some flowers smell sweet and are bright white, that's because they try to attract animals who are active at night. White is the most visible color and the smell will attract them. Other flowers are very colorful and smell nothing, they attract different pollinators. Some smell like an animal carcass.

There is actually no sweet smell, it is just fresh. We are so used to smelling exhaust and stuff, we don't get to smell many things that are fresh. Also when you make a woman happy by sending/giving flowers, they think everything smells good for a couple of hours. Good luck men.

The great variety of delicate and beautiful flowers has inspired the works of many poets, especially from the Romantic era. Famous examples include and William Wordsworth's I Wandered Lonely as a Cloud and William Blake's Ah! Sun-Flower:
Ah, Sun-flower weary of time,
Who countest the steps of the Sun,
Seeking after that sweet golden clime
Where the traveler’s journey is done:
Where the Youth pined away with desire,
And the pale Virgin shrouded in snow
Arise from their graves, and aspire
Where my Sun-flower wishes to go.
—William Blake, Ah! Sun-Flower
Because of their varied and colorful appearance, flowers have long been a favorite subject of visual artists as well. Some of the most celebrated paintings from well-known painters are of flowers, such as Van Gogh's sunflowers series or Monet's water lilies.
The Roman goddess of flowers, gardens, and the season of Spring is Flora. The Greek goddess of spring, flowers and nature is Chloris.

Who told you all flowers smell sweet. There are lot of foul smelling & non-smelling flowers. As every living being has its own natural trait flowers also have one.

Colorful and aromatic petals (aromatic oils) of the angiosperms (flowering plants) co-evolved with the pollinators (insects & birds primarily) to enhance the angiosperms' land-based sexual reproduction while feeding the pollinators some nector. Thus angiosperms became very successful very quickly and the accompanying adaptive radiation had them become dispersed all over the planet.

1 not all flowers smell sweet some give of a awful smell. On bees and insects fiund them by thier color and giving of oxygen
the smell that wat if some animals and brids are nearby including himing birds to either pollinate them or arrtact stinning isnects to portect them from a critter that might want ot eat it . this is a symbiotic realtionship the stigning insects get pollen the palnsts get protection .
it is called evolution

hi, relies upon the place you reside. in case you reside in a hotter place interior the US, try Jasmine, the form that vines, it grows numerous inches each and every day and has extra flowers than leaves! The smell will fill your backyard like loopy! Now in case you reside up north, Gardenia timber are basic to boost, additionally think ofyou've have been given to attempt growing to be some Mint and Basil, they boost so speedy and so aromatic, to not point out the reality which you will cook dinner with them too!

flowers smell sweet so that insects will pollenate them, the flowers that smell sweet will often be brightly coloured for the same reason. however some flowers are not sweet smelling or brightly coloured, this is because they are wind pollunated.

from what i remember from my horrible science lessons, the teacher says it was to attract bees for the sake of pollination etc. I don't remember the rest, i must have dosed off then, gosh the teacher was terrible. Anyway, the bees will then take the pollen to another flower etc
