The pollen grain produces a pollen tube that grows towards the ovule in order to deliver the male gametes for fertilization. Once the pollen tube reaches the ovule, the male gametes are released to fertilize the female gametes inside the ovule, leading to the formation of seeds.

Where does the pollen tube go?
It goes in the stigma, which is what catches the flying pollen in the air, and it's also the sticky regimen.
How does fertilisation occur in flowers?
Have you ever wondered what are all those bees and hummingbirds looking for inside the flowers. Well it is a sweet substance that the plant provides for them called nectar. The nectar is advertized by the petals. When the animal goes for the nectar, the flower passes on the pollen to it. That is why if you look carefully you´ll see a yellow dust all over them. That is the pollen. Since they will need to get more nectar, the animals go searching for another flower and during that process they transfer the pollen from flower to flower. The pollen is collected by the flower´s stigma and flows down the style and into the ovary were it will fertilize the ovule. Amazing!
How does the process of fertilisation take place in flowers?
the stamen[male] part of the plant creates a solution called pollen. a insect will come along and when it gets close some of the pollen rubs on the insect. then while it is looking around the flower some of the pollen rubs off on the pistil [female part of the plant]. pollen then go down into the ovary where the eggs are and then the eggs and the pollen combine to form seeds
Describe sexual reproduction in plants?
In flowering plants (Angiosperms), the pollen grain from the male plant is dispersed viawind, insect pollinators and animals. The pollen grains eventually reach the female plant.Once the pollen grain is in the flower it creates a pollen tube to be deposited into theflower's ovule. One sperm fertilizes the egg while the other one fertilizes two polar nuclei,giving rise to an endosperm (3n) - a food supply for the zygote. Eventually the zygote willbe dispersed, and a new flower will be born.It occurs when the pollen from an anther is transferred to the stigma. The pollen grain germinates, grows down the style and fuses with the ovule. The fertilized ovule develops into the embryo which finally becomes a seed.pollen get stuck to things such as when bees and birds get nector it gets on them and when the go to the next plant they leave pollen from the previous flower on itThe same process used by humans. The female sits on the males face and farts until the male poops a baby.
What is the difference between pollination and fertilization in plants?
Fertilization is the union of of human egg and sperm cells. It is uncertain exactly what people may mean by conception. Conception may mean the same as fertilization or it may mean point where the connection is made to the walls of the womb by the zygote. The word does not have a hard definition as it is a debate point between the Pro-Life and Pro-Choice factions about exactly when life begins.

Where do the pollen grains go after pollination?
After pollination, the pollen grains germinate on the stigma and grow a pollen tube down the style to reach the ovule. The pollen tube delivers sperm cells to fertilize the egg cell within the ovule, leading to the formation of a seed.

How close to the egg can the pollen grain get?
when a pollen grain lands on the stigma it creates a pollen tube that goes down to the egg where sperm fuzes with the egg.
Where does pollen came from?
i think that probably the came from the ovule of the flower and the go all the way up to the stigma
What is the process that happens when pollen meets an egg?
The pollen which is made by the anther which belongs ti the stamen meet with an ovule (the female egg cell) as it goes down the style it shall go in the ovary in the carpel (the female part of the flower) and soon meet the ovule and start making seeds.

What is fertilisation in plants?
In plants, fertilization is a process of sexual reproduction, which occurs after pollination and germination.Fertilization can be defined as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote. It is a physicochemical process which occurs after the pollination of the carpel. The complete series of this process takes place in the zygote to develop into a seed.In the fertilization process, flowers play a significant role as they are the reproductive structures of angiosperms (flowering plants). The method of fertilization in plants occurs when gametes in haploid conditions fuse to produce a diploid zygote.In the course of fertilization, male gametes get transferred into the female reproductive organs through pollinators (honey bees, birds, bats, butterflies, flower beetles) and the final product will be the formation of the embryo in a seed.Fertilization ProcessIn flowers, the pollen grain germinates after the pollination of the carpel and grows into the style by creating the pathway for the pollen grain to move down to the ovary.The pollen tube opens into the ovule through the micropyle and bursts into the embryo sac. Here, the male nucleus unites with the nucleus of an egg inside the ovule forming a diploid zygote, which later swells up and develops into a fruit.Types of FertilizationFertilization process can be grouped into three types and are classified mainly based on the entry of the pollen tube into the ovule.PorogamyIt is the common type of fertilization carried out in all angiosperms or flowering plants. In this type of fertilization, the pollen tube enters the ovule through the micropyle.ChalazogamyThis type of fertilization is carried out on all Casuarina species of plants. In this condition, the pollen tube enters the ovule through the pollen tube.MesogamyThis type of fertilization is seen in all Cucurbit plants, such as pumpkin, ridge gourds, bitter gourd and other gourd plants. In this type of fertilization, the pollen tube enters the ovule through its middle part or through the integuments of the ovule.Double FertilizationDouble fertilization is a process of fertilization characterized by the fusion of a female gametophyte with two male gametes. In this mechanism, one sperm cell fuses with the egg-producing zygote, and the other fuses with the two polar nuclei to make the endosperm. All angiosperm plants undergo double fertilization process.Seed plants can go through the process of fertilization, when seedless plants cannot. If the seedless plants do go through fertilization they would require a flower for fertilization to occur.
What is the difference between pollen and pollen grain?
Pollen refers to the microscopic reproductive structures produced by plants, while pollen grains are the individual units that carry the male gametes. Pollen grains are released from the anthers of flowers and are carried by wind or pollinators to fertilize the ovules of plants.

Where does pollen go on a flower?
Pollen is in the stamen, which is the male part of the flower. After pollenation, it goes to the pistil, the female part. During fertilization, it moves downward, to the ovule, still inside the pistil. There are several stamen on one flower, the exact number depends on the type of flower. They surround the pistil, which is shorter. Sorry if I answered a simple question with an essay. I tend to do that.
