what is the male part of a flower called

Flower is one of the age-old words we learn, and a axiological allotment of our every day lives. Flowers may be the best accepted anatomy of attributes we appointment on a circadian basis, and yet back we try, they are decidedly adamantine to define.

We acquaint the catechism on the BBC Earth Facebook folio to see if any of our readers had the answer.

A flower, says Kevin Drucas, is an adjustment that "was so acknowledged that over the aftermost 200 actor years they radiated, speciated, climbed up into trees, cliffs, hid below snow … alike battled pathogenic fungi and insects", adding, "one could say flowers accept baffled every abode on Earth".

A annual is "a actual apparent beastly organ"

Other bodies acquainted a added airy accord to the flower. "A annual is to a bulb as eyes are to a person...expressive, beautiful, aerial yet strong," says Kristy Hardage Launius, while Valerie Wakefield describes flowers as "magic, beauty, abundance".

Many bidding the activity that there is article ambiguous about the flower.

"Describing how I feel about blooming flowers is like acknowledgment my soul...how do I put it into words?" says Naomi Sunczyk.

"What are flowers? We aloof don't know," says Jeff Schultz.

The annual is so adamantine to ascertain that alike scientists are still discussing it.

Over the accomplished year, the account Botany Letters has arise a alternation of accessories discussing how best to ascertain a flower.

There are over 350,000 accepted breed of beginning bulb

Most simply, a annual is "a actual apparent beastly organ", says Marc-André Selosse, Professor of bulb change at the National Museum of Accustomed History in Paris. Flowers are amenable for the bearing the abutting bearing of plants. "The barter of beastly cells, which are anchored in the pollen, is agitated out by wind or, best often, animals," Selosse says.

Each annual is fabricated up of the changeable changeable parts, accepted as carpels, and a macho allotment alleged the stamen. These are amidst by petals, which are in about-face amid by sepals.

But not all plants accept flowers: abandoned beginning plants, or "angiosperms", do. What's more, there are over 350,000 accepted breed of beginning plant, and their flowers accomplish every apprehensible shape, colour and scent. So we charge to dig a little deeper.

The naturalist Carl Linnaeus was amid the aboriginal to try to allocate this diversity. "[Linnaeus] had lots of plants to study, including abounding from biodiverse regions," says Mark Chase, Senior Research Professor at the Royal Botanic Gardens, Kew in the UK.

Abounding plants that accept agnate flowers about-face out to be abroad ancestors

In his 1753 book Systema Naturae, Linnaeus classed angiosperms based on the characteristics of their flowers. This was useful, but it abandoned went so far.

Modern botanists are absorbed in the ancestors timberline of beginning plants, accepted as a phylogeny. This tells us who is accompanying to whom, the aboriginal footfall in compassionate how flowers evolved. But back amalgam a ancestors tree, appearances can be deceiving.

Chase is allotment of the Angiosperm Phylogeny Group (APG), which he describes as "a bunch of botanists who summarise the abstruse and anatomy phylogenetic after-effects in a arrangement of classification." They mostly use abiogenetic data, which is added reliable for compassionate how breed are accompanying than their concrete appearance.

The APG's allocation was aboriginal arise in 1998, and was best afresh adapted in March 2016. It differs from Linnaeus's absolutely dramatically.

Many plants that accept agnate flowers about-face out to be abroad relatives. The plants had apart stumbled aloft the aforementioned floral design.

All flowers ultimately accept the aforementioned purpose – pollination

Plants that allure the aforementioned affectionate of pollinator generally assemble on agnate annual designs. For instance, flowers that allure beetles generally accept assorted stamens, which access the affairs that the beetle will backpack pollen abroad on its body.

In fact, annual characteristics may be the atomic accessible appropriate for classifying angiosperms.

When beginning plants aboriginal evolved, about 130 actor years ago, they underwent a aeon of actual accelerated evolution, during which abounding new forms of annual appeared. Charles Darwin declared the abrupt actualization of beginning plants as an "abominable mystery", because he could not brainstorm how accustomed alternative could accept acted so fast.

But this accelerated change makes added faculty if we accept the flower, not artlessly as a changeable organ, but as a abode area plants and animals charge meet.

All flowers ultimately accept the aforementioned purpose – pollination. Although bees are the best acclaimed pollinator, flowers can additionally be pollinated by beetles, flies, butterflies, and alike birds and bats.

"Flowers," as Warren McDonald puts it, "are the abbreviate skirts of the bulb kingdom. They acquaint that article central needs to be pollinated."

Red flowers are added acceptable to address to collywobbles and birds

A annual is "the aerial articulation amid the bulb and beastly kingdoms," says Adisha Kariyawasam. Similarly, Felomena Chart says that flowers are a "very important allotment of [an] ecosystem. Afterwards flowers, there will be no bees or carnality versa. No pollinator, no food."

To be successful, a annual needs to aftermath pollen, as able-bodied as a accolade such as nectar, and it charge be adorable to the appropriate animals. The assortment of size, shape, colour and aroma beyond beginning plants reflects the abounding agency to allure an beastly pollinator.

Angiosperms accept tailored their flowers to the specifics of their alleged pollinator, abnormally authoritative abiding the annual appeals to their beheld system, that the aroma is best up by their faculty of smell, and that the annual is the appropriate shape, admeasurement and architecture to fit their body.

These agrarian flowers may be ambrosial to animal eyes, but this is little added than a coincidence.

Bees can see dejected and blooming light, but they abridgement our adeptness to analyze red. However, clashing us they can additionally see ultraviolet light, and abounding flowers accept acquired to accomplishment this.

About one third of all acclaim breed action no accolade to their pollinator

One abstraction of 180 altered breed of annual begin that they tend to abatement into one of three colours – UV or violet, blue-green or red. Two of these categories, UV and green, accord to the wavelengths perceived by bees. Red flowers are added acceptable to address to collywobbles and birds, which can see a added spectrum of red colours.

Flowers that allure added types of pollinator accept to apply altered approaches. For example, abounding bat-pollinated plants annual at night, and focus on aroma rather than looks to allure pollinators in the dark.

But the three actualization of flowers – pollen, accolade and allure – are not necessarily linked. It is accessible to advance some but not all of these traits, and this leaves opportunities for cheating and conflict.

Around one third of all acclaim breed action no accolade to their pollinator. Instead, they focus on the allure allotment of the blueprint – artful the actualization and aroma of a changeable of their pollinator's species.

Flowers are evolving and counter-evolving in acknowledgment to addition living, evolving breed

For example, the bee acclaim has acquired petals and sepals that resemble a changeable bee agriculture on a flower. Confused macho bees blend the annual while aggravating to acquaintance with it. Bee orchids accept additionally been begin to actor pheromones produced by changeable bees.

Similarly, abounding hummingbird breed accept been begin to abduct ambrosia from flowers afterwards pollinating the flower.

But the angiosperms do not booty this affectionate of behavior lightly: they accept acquired mechanisms to accomplish cooperation. For instance, academician flowers accept a lever-like stamen that armament any insect entering the annual to aces up pollen afore they can get to the nectar.

This leads us to addition appearance of the flower: it is a battleground.

Selosse argues that accelerated change in flowers should be accepted because they are the sites of inter-species interactions.

Pollinating animals like bees appointment flowers, and the annual needs to ensure that back they do they aces up pollen. This agency flowers are evolving and counter-evolving in acknowledgment to addition living, evolving species.

Anniversary breed charge advance as fast as it can, aloof to accumulate up with the added

That is article that abounding scientists accept tends to aftereffect in added accelerated evolution. And accelerated evolution, Selosse says, increases the affairs that the aforementioned evolutionary innovations will arise afresh and again.

This abstraction is accepted as the Red Queen hypothesis, afterwards Lewis Carroll's archetypal book Alice's Adventures in Wonderland. In the story, the Red Queen runs a amaranthine chase because "it takes all the active you can do, to accumulate in the aforementioned place".

When two breed advance and counter-evolve in an "arms race", as happens with flowers and cheating pollinators, anniversary breed charge advance as fast as it can, aloof to accumulate up with the other.

"The alternation is evolutionarily dynamic," says Selosse. "This atrocious appearance of ecosystems and change may be advantageous back we anticipate about the dynamics of life."

However, there is yet addition way to anticipate of flowers.

Although flowers appearance absurd diversity, back you band abroad the capacity they all accept the aforementioned basal structure. This is the abstract, concrete analogue of a flower.

Lacandonia schismatica is the vampire of the bulb apple

With abandoned a scattering of exceptions, all flowers accommodate to the basal ABC archetypal of development, which was aboriginal declared in 1988.

As a annual forms, anniversary corpuscle charge be assigned a role. During development, the absorption of altered proteins in anniversary corpuscle determines whether they will become a blade cell, allotment of the stamen, or article else.

An absolute annual can be produced from aloof three genes. "A" proteins abandoned aftermath a sepal cell, while A and "B" calm accomplish blade cells. "C" proteins ascendancy the carpels and the stamen: C abandoned produces carpel cells, while C and B calm anatomy stamen cells.

There is one annual that does not chase the archetypal ABC layout. It addled botanists for decades, but it turns out to be the barring that proves the rule.

Lacandonia schismatica is the vampire of the bulb world. It is absolutely white because its beef accommodate no chlorophyll – the blooming basal of bulb beef that performs photosynthesis. Instead of agriculture on sunlight, this abject bulb feeds on fungi.

Afore flowers appeared, best plants reproduced like avant-garde ache copse

Its flowers are peculiar, in that the macho and changeable genitalia are inverted: the stamen is in the centre with the carpels about it.

This was a addle until absolutely recently. A abstraction in 2010 begin that the astern annual was acquired by a mutation, which causes B genes to be bidding in the centre of the flower; ACB rather than ABC.

Because the ABC archetypal is aggregate by about all beginning plants, we can accept that the aboriginal annual had this basal structure. But we will apparently never apperceive what the aboriginal annual looked like.

Before flowers appeared, best plants reproduced like avant-garde ache trees.

These plants aftermath either macho or changeable pinecones. Macho pinecones accommodate pollen, which is agitated abroad on the wind and hopefully acreage on a changeable pinecone, which again produces seeds.

I can't brainstorm a apple afterwards flowers. It would be ugly, dim, and sad

This adjustment of reproduction bedeviled for about 200 actor years.

What the aboriginal annual looked like is "still a actual abundant accessible question" says Chase. Nobody is abiding which age-old plants gave acceleration to the beginning plants.

The aboriginal annual may accept been a adapted cone. A abstraction in 2009 begin that avocados – a almost aboriginal annex on the ancestors timberline of beginning plants – still harbour the genes that would accept produced cones. The genes accept artlessly been adapted to instead aftermath a flower.

So we can ascertain a annual in evolutionary terms, as a accurate structure, and as a way for plants and animals to interact. But there is one final element: the animal angle.

Felomena Chart says: "I can't brainstorm a apple afterwards flowers. It would be ugly, dim, and sad."

Several able roses accept alert as abounding petals as agrarian roses

Flowers are "a attribute of attributes and 'wilderness'," says archaeologist Elisabeth Dodinet of the University of Toulouse II in France. They "are additionally allotment of our wellbeing now on a added aesthetic, acute level, as a antidote to abate our urbanised way of life."

Flowers aboriginal acquired cultural acceptation back our civilisations became added developed and urbanised, says Dodinet. In the West, our adulation of flowers blossomed in the 18th Century, but beforehand adult societies in China and Japan saw them as symbols of beauty, leisure and rarity.

But it is not a one-way street: our adulation of flowers has additionally had a huge appulse on flowers themselves. Over the centuries we accept artificially alleged for flowers that we like to attending at, to smell, or in some cases to eat.

For instance, the agrarian alacrity bulb is a delicate, camouflaged yellow-flowered bulb from the Mediterranean. Over abounding generations, it has been shaped by bodies to accomplish what we now apperceive as cabbage, broccoli, kale and cauliflower. These avant-garde vegetables, which all accord to the Brassicaceae family, attending annihilation like their agrarian ancestors, demonstrating the absurd evolutionary adaptability of flowers.

Flowers aboriginal acquired cultural acceptation back our civilisations became added developed and urbanised

Roses accept additionally been afflicted by bogus selection. Several able roses accept alert as abounding petals as agrarian roses, and a 2010 abstraction articular the alteration responsible. Bulb breeders in Europe and China had apart alleged for mutations in the aforementioned gene, consistent in added petals and prettier roses.

Our accord with the annual has fundamentally afflicted plants at the genomic level. It has alike fabricated some breed sterile, breaking the pollination articulation that some abounding of us anticipate of back we account a flower.

The annual is our abutting articulation to nature. As our societies became added burghal and we grew more afar from the accustomed world, it became an important attribute of life, animation and wildness. But the adorableness of the annual disguises the evolutionary conflicts it harbours.
