When does a flower become "officially" pollinated? Thank You?

Question

Where does the pollen fall, or what exactly happens for a flower to be "officially" pollinated

Answer 1

Or is it when the sperm enters the egg?

Answer 2

Would i be right in saying to have some plants that are both male and female? Containing both stigma and anthers. Ergo, a bee will drop on a plant get nectar, and pick up pollen then go to another plant of the same kind, accidentally drop off the pollen onto the stigma, get more from the anthers and more nectar from the stigma?

:]

Answer 3

The flower is pollinated when pollen has been transferred to the stigma of the pistil.  Some flowering plants have pollen transferred by wind, others by specific insects (e.g., bees and wasps), and others by birds (e.g., hummingbirds).

When a pollen grain lands on a receptive stigma, it germinates and a tube grows through the stigma, style, and ovary wall until it reaches the micropyle, the opening of the ovule inside the ovary.  Fertilization #1 is when one sperm from the pollen tube fuses with the egg.  Fertilization #2 is when the second sperm from the pollen tube fuses with the two polar nuclei in the central cell of the embryo sac (aka megagametophyte) to form the primary endosperm nucleus.

Answer 4

The Pollen falls right here for me. If it's good Pollen you want then Dutch is the best ! It is recommended to be regularly pollenated and I am living proof of that fact.

Answer 5

Pollen from other plants in a form of powder is carried by wind, bees and birds and  as they land on a plant the powder attaches itself to the flowers starting the pollination process

Answer 6

Pollination is an important step in the reproduction of seed plants: the transfer of pollen grains (containing the male gametes) to the plant carpel, the structure that contains the ovule (female gamete). The receptive part of the carpel is called a stigma in the flowers of angiosperms and a micropyle in gymnosperms.

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

Hope this helps :)

Answer 7

a bee gets the pollen from a male flower all over its body. from a part of the flower in the center called the pistol.  then when that same bee lands on a female flower he gets the pollen on the stamen.  At that point the flower is pollinated.

Answer 8

So when a mommy flower and a daddy flower love each other very much.....j/k!

Generally, pollen from flower anthers (male flower part) gets deposited on the stigma (female flower part) by a pollinator, which can be a bee, bird, fly, etc. The stigma is the column usually in the middle of the flower, which may have a sticky nectar on it to help make pollen stick.

Pollen is similar to human sperm in that it is like a capsule containing genetic information. When it sticks to the stigma, a chemical reaction causes a "pollen tube" to bore a hole through the style (the stalk of the stigma) down to the flower's ovary, where its eggs are. The genetic material in the pollen grain then moves down the pollen tube, where it meets the egg.

Official pollination is when the pollen dna meets egg dna.
