One proposed reason for the sudden, fully developed appearance of flowers is that they evolved in an isolated setting like an island, or chain of islands, where the plants bearing them were able to develop a highly specialized relationship with some specific animal a wasp, for example , the way many island species develop today.
This symbiotic relationship, with a hypothetical wasp bearing pollen from one plant to another much the way fig wasps do today, could have eventually resulted in both the plant s and their partners developing a high degree of specialization. Island genetics is believed to be a common source of speciation , especially when it comes to radical adaptations which seem to have required inferior transitional forms. Note that the wasp example is not incidental; bees, apparently evolved specifically for symbiotic plant relationships, are descended from wasps.
Likewise, most fruit used in plant reproduction comes from the enlargement of parts of the flower. This fruit is frequently a tool which depends upon animals wishing to eat it, and thus scattering the seeds it contains. While many such symbiotic relationships remain too fragile to survive competition with mainland organisms, flowers proved to be an unusually effective means of production, spreading whatever their actual origin to become the dominant form of land plant life. Flower evolution continues to the present day; modern flowers have been so profoundly influenced by humans that many of them cannot be pollinated in nature.
10 Beautiful Flowers That Kill In Horrifying Ways - Listverse
Many modern, domesticated flowers used to be simple weeds, which only sprouted when the ground was disturbed. Some of them tended to grow with human crops, and the prettiest did not get plucked because of their beauty, developing a dependence upon and special adaptation to human affection. Many flowering plants reflect as much light as possible within the range of visible wavelengths of the pollinator the plant intends to attract. Flowers that reflect the full range of visible light are generally perceived as white by a human observer.
An important feature of white flowers is that they reflect equally across the visible spectrum. While many flowering plants use white to attract pollinators, the use of color is also widespread even within the same species. Color allows a flowering plant to be more specific about the pollinator it seeks to attract. The color model used by human color reproduction technology CMYK relies on the modulation of pigments that divide the spectrum into broad areas of absorption. Flowering plants by contrast are able to shift the transition point wavelength between absorption and reflection.
If it is assumed that the visual systems of most pollinators view the visible spectrum as circular then it may be said that flowering plants produce color by absorbing the light in one region of the spectrum and reflecting the light in the other region.

With CMYK, color is produced as a function of the amplitude of the broad regions of absorption. Flowering plants by contrast produce color by modifying the frequency or rather wavelength of the light reflected. Most flowers absorb light in the blue to yellow region of the spectrum and reflect light from the green to red region of the spectrum. For many species of flowering plant, it is the transition point that characterizes the color that they produce.
Color may be modulated by shifting the transition point between absorption and reflection and in this way a flowering plant may specify which pollinator it seeks to attract. Some flowering plants also have a limited ability to modulate areas of absorption.
This is typically not as precise as control over wavelength. Humans observers will perceive this as degrees of saturation the amount of white in the color. Many flowers have important symbolic meanings in Western culture. Some of the more common examples include:. 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.
Flowers are also dried, freeze dried and pressed in order to create permanent, three-dimensional pieces of flower art. Flowers within art are also representative of the female genitalia , [32] as seen in the works of artists such as Georgia O'Keeffe , Imogen Cunningham , Veronica Ruiz de Velasco , and Judy Chicago , and in fact in Asian and western classical art. Many cultures around the world have a marked tendency to associate flowers with femininity. The great variety of delicate and beautiful flowers has inspired the works of numerous poets, especially from the 18th—19th century Romantic era.
Their symbolism in dreams has also been discussed, with possible interpretations including "blossoming potential". The Roman goddess of flowers, gardens, and the season of Spring is Flora. The Greek goddess of spring, flowers and nature is Chloris. In Hindu mythology, flowers have a significant status. Vishnu, one of the three major gods in the Hindu system, is often depicted standing straight on a lotus flower. In modern times people have sought ways to cultivate, buy, wear, or otherwise be around flowers and blooming plants, partly because of their agreeable appearance and smell.
People therefore grow flowers around their homes, dedicate entire parts of their living space to flower gardens , pick wildflowers, or buy flowers from florists who depend on an entire network of commercial growers and shippers to support their trade. Flowers provide less food than other major plants parts seeds , fruits , roots , stems and leaves but they provide several important foods and spices.
Flower vegetables include broccoli , cauliflower and artichoke. The most expensive spice, saffron , consists of dried stigmas of a crocus. Other flower spices are cloves and capers. Hops flowers are used to flavor beer. Marigold flowers are fed to chickens to give their egg yolks a golden yellow color, which consumers find more desirable; dried and ground marigold flowers are also used as a spice and colouring agent in Georgian cuisine.
Flowers of the dandelion and elder are often made into wine. Bee pollen , pollen collected from bees, is considered a health food by some people. Honey consists of bee-processed flower nectar and is often named for the type of flower, e.
Hundreds of fresh flowers are edible but few are widely marketed as food. They are often used to add color and flavor to salads. Squash flowers are dipped in breadcrumbs and fried.

Edible flowers include nasturtium , chrysanthemum , carnation , cattail , honeysuckle , chicory , cornflower , canna , and sunflower. Some edible flowers are sometimes candied such as daisy , rose , and violet one may also come across a candied pansy. Flowers can also be made into herbal teas. Dried flowers such as chrysanthemum, rose, jasmine, camomile are infused into tea both for their fragrance and medical properties.
Sometimes, they are also mixed with tea leaves for the added fragrance. Flowers have been used since as far back as 50, years in funeral rituals. Many cultures do draw a connection between flowers and life and death, and because of their seasonal return flowers also suggest rebirth, which may explain why many people place flowers upon graves.
In ancient times the Greeks would place a crown of flowers on the head of the deceased as well as cover tombs with wreaths and flower petals. Rich and powerful women in ancient Egypt would wear floral headdresses and necklaces upon their death as representations of renewal and a joyful afterlife, and the Mexicans to this day use flowers prominently in their Day of the Dead celebrations in the same way that their Aztec ancestors did.
