How is the flower pollinated?Why?

by insects like bees and butterflies...\nthat are attracted by its nectar...\nwhen it flies from flower to flower to collect more nectar, it pollinates other flowers with the pollen it has on its legs...\nit is a very smart ploy by the flowers isn't it?

i'd like to take this time to give a biology lesson. you/everybody else is horny because its spring time. the pollenation affects hormones.

some plants have hook shaped fruits.. it can hook onto animals n be carried off to different places\n\nDandelion has light featherlike seeds exposed to air that can be blown off with the wind\n\nPlants near waterbodies have seeds that can float on water.. so again they can be deposited in far off places\n\nThere r various other adaptations in the links below.. check em out..

the sun flowers. they are used exactly for that purpose, in order to remove theese elements from the soil!

If it is the same species of flower, the pollen lands on the stigma (easy to remember...stigma ma mother ei female / stamen....men....male) a chemical reaction occurs that makes the pollen develop a tube/ straw that leads down the stigma to where the seeds are...get a text book out for this cant remember the name of that thing....the DNA is then taken up by the flower in the production of the seed....Oooo dear so many years ago.....cant remember a thing properly

Any part of a plant has aromas, not just the flower, but the flower is the sexual stage of the plant and has to attract the help of the pollinators! But the most "famous and loved" aromas are found within the vacuoles within the cells of the cbeautifully olorful petals of flowering plants.  These contain the most natural aromatic floral oils (which cause the aromas) that we can smell; aromas-scented oils were basically "designed by nature" to attract the birds-bees-pollinators; fruits produce aromas-aromatic oils too.(fruits are just pregnant flowers, the "swollen" ovaries of the stigma)

It's pollen from flowers which has been packed together by bees and brought into the hive.

Nectar certainly does ferment in flowers. It's quite common in  tropical regions where the warm temepratures accelerate fermentation to see birds drunk as skunks literally falling out of flowering trees. Drunk birds also become belligerent and commmonly attack each other.\n\nSo the idea that a bee can become drunk is entirely plausible, though I've never noticed it myself.

A flower is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called sperms). The flower structure contains the plant's organs, and its function is to produce seeds through reproduction. 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. After fertilization, portions of the flower develop into a fruit containing the seeds.\nThe 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.

It is to catch pollen, so that the female plant can become pollinated. The polyps are called glandular trichomes. They contain the resin which has the highest concentration of THC , the psychoactive drug material of the cannabis plant.\nOnly the female plants are covered with resin.\nThe males are taller, tougher and make little white flowers instead of buds. The flowers open and release pollen. When the pollen lands on a female bud, that bud will produce a seed. \nMarijuana has been cultivated by humans for a long time. A high resin content makes the plant more desirable for cultivation by humans, therefore every cannabis breeder is selecting for a high resin content.\nThe resin also protects the flowers of the female plant from drying out.

the part of flower that gets converted to fruit on fusing with sperms from the pollen grains is the ovary... the ovules inside the ovary gets converted into seeds

Like the Dude said above.. they have flowers above the water.\nFlowers get pollinated, seeds grow, seeds are distributed thru the water, fall to the bottom and grow the next generation... its a circle of life thing.

It comes up as a tight green bud, opens into a bright yellow flower, then the flower withers and the poofy seed things develop, ready to carry the seeds somewhere else so the whole process can begin again. \nYou are 100% correct in this. \nWhere do you live that there aren't dandelions around to demonstrate? In our yard, they grow year round and they are very vigorous in their growth.

the flower is what separates it from other plants, attracting birds and insects to pollenate the plant. however the plant requires all of its "parts" for survival, eg leaves with chlorophyll for photosynthesis, roots for water and ion uptake, and the stem with the xylem and phloem for water nutrient transport. so, no part is superior to another, but the flower appears to be the most "advanced" part.

im afraid only bee pollen can be bought, so if you need to study pollen grains not contaminated by bee material, you have to collect it - not difficult. pine pollen is easiest to collect but virtually to impossible to cultivate into pollen tubes. the easiest to cultivate is tobacco pollen - tobacco is and equivalent to guinea pig in plant biology. somewhere it is restricted to cultivate tobacco unless u are a corporate body, though. maize pollen is also good - has large grains. quantitative chemical analyses are made more comlicated due to very resistant outer surface. generally pollen can be stored in -20 degrees of celsius, not more not less. write me email if you are serious bout it. what kind of research do u have in mind?

because it is much easier to use their stems for budding and grafting than using the seeds. When pollen is applied to the female pads and a pod forms, it is usually a couple of months until the pod ripens and exposes its seeds where as budding and grafting will only take a few weeks.futhermore getting a pod to form on a plant can be very difficult -- 60-80F degrees, high humidity and "willing" parents. After the seeds have germinated and been raised to maturity, 6 to 18 months, they will produce a flower (and bush) with qualities from both the pollen and the pod parent. Budding and grafting will only take 6 to 8 weeks and the procedure is simple.

Bee, fly AND moth flowers offer a nectar reward to the insect while wind pollinated flowers have very little or no nectar.  Grasses are wind pollinated and have no nectar.  Moth pollinated flowers are very long because moths have long probiscuses.  The flower has to be long so the moth gets close enough to get pollen on it's body.  Bee and fly flowers are shorter because the insect enters the flower completely to get nectar.
