Pollen is transferred from the stamen (male reproductive organ) to the pistil (female reproductive organ) by various methods such as wind, insects, birds, or other animals. This transfer of pollen is essential for fertilization to occur and for the plant to produce seeds.
Anther pollen refers to the pollen grains produced by the anther, which is the male reproductive organ of a flower. These pollen grains contain the male gametes needed for fertilization when they land on the stigma of a flower.
Some of the pollen grains carried by wind,insects,birds or bats may reach a carpel and stick to the ripe stigma.Each pollen grain produces a tiny tube which grows down to the style,into the ovary and towards the ovules or egg cells.when one of the tubes reaches an ovule,it bursts open.A male nucleus from the pollen grain then moves down the pollen tube to join with the nucleus of the female sex cell,the ovule.when the nuclei of the pollen grains and ovules have joined together, the ovules are said to be fertilized.
The tube nucleus in the pollen tube typically disintegrates as it moves downwards in the pollen tube to ensure that the sperm cells reach the ovule without interference. This allows for successful fertilization to occur by facilitating the fusion of the sperm cells with the egg cell and central cell in the ovule.
A pollen grain's surface is often rough and sticky, allowing it to adhere to an insect's body as it moves from flower to flower. Additionally, the shape and size of pollen grains match well with insect hairs, making them easy to brush off as the insect travels. Lastly, the lightweight nature of pollen grains makes them easily dispersed by the movement of insects.
Bees help flower reproduction by transferring pollen from one flower to another as they forage for nectar. This transfer of pollen between flowers allows for fertilization to occur, which is necessary for the development of seeds and fruits in the plant. This process, known as pollination, is essential for the reproduction and genetic diversity of many plant species.
The transfer of pollen grains from the stamen to the pistil is called pollination.
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.
-pollen sticks to the stigma at the end of the pistil -pollen tubes grow down the pistil to the egg cells -sperm cells from the pollen moves down the tubes -fertilization combines DNA

Pollen
1. Many flowers have both male and female parts. So some flowers can indeed pollinate themselves, and the pollen moves from the stamens to the pistil on the same plant. This is called self pollination. Most flowers, however, are cross pollinating. This means the pollen must be carried from the stamens of one plants to the pistil of another plant of the same kind.
Pollination
When an insect like bee's lands on a flower, pollen sticks to it's legs. So when an insect moves to another flower pollen gets on that flower and so on and so on as the insect moves from one plant to another.
Wind moves pollen for some plants like grass and corn. Animal pollinators move pollen for many flowering plants.

Anther pollen refers to the pollen grains produced by the anther, which is the male reproductive organ of a flower. These pollen grains contain the male gametes needed for fertilization when they land on the stigma of a flower.
