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!
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.
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
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.
Why is it important to elevate the anthers?
The anther is important in a flower because that is where the pollen grains are produced and kept, and pollen is vital for redproduction. This is very important for reproduction and controlling reproduction.
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 the difference between pollen and pollen grain?
Microscopic differences in shape and size.

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.
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.
When was Don't Go Against the Grain created?
Don't Go Against the Grain was created in 1996.
Why doesva flower have so many pollen grains than ovules?
flowers produce more pollen grains because the anther makes the pollen it then the stigma collects pollen and the petals of flowers atract insects or birds.
