The pollen grains from the stamen (male part) of the flower are transferred to the carpel (female part) of another flower to pollinate (fertilize) that flower.
It is called as pollination. Here the pollen grains are transmitted from one flower to other flower. Pollen grains may be transmitted in the same flower from the stamen to stigma.
The anther produces pollen grains which would be transferred to other plant's stigma which will receive the pollen grains when an insect fly pass it then the pollen grains will be stuck on its wings.
Self pollinationWhen pollen grains from a flower are carried to the stigma of the same flower or on the other flower of the same plant, the phenomenon is called self pollination.Cross pollinationWhen the pollen grains from a flower are carried to the stigma of the flower on other plant, the phenomenon is called cross pollination.
pollen grains are transported from the microsporangium (contained in the anther of an angiosperm flower, male cone of a coniferous plant, or male cone of other seed plants)
When man touches any flower,the some particles of the pollen grains sticks to the man's hand,nd when that man touches any other flower,the pollen in his hand transfers to the other flower, and pollination takes place
insects play a major role in pollination by transferring pollen grains from one flower to other flower.eg: honey bee
Pollinators are attracted to the nectar. When they are feeding on the nectar, they pick up pollen and/or deposit pollen. The location of the nectaries is such as to make the pollinators touch the pollen to pick it up or to deposit it.
because
pollen grains are the male gametes .And if there wont be any pollen then what will fuse with the female gamete.................... Thus female gametes need pollen to reproduce as with out it there wont be any flowers in the world In other words the pollen fertilizes the ovary, in order to create a new flower :):) xxx
When pollen grains from the flower of same plant land on the stigma of same flower or other flowers of the same plant, it is called self-p0llinating of a plant.
There is a symbiotic relationship between a crab spider and a flower. The crab spider carry pollen grains to the other flowers when gathering nectar on these flowers.
They carry pollen from flower to flower the pollen from one flower fertilizes other flowers and so on.
