pollination

the transfer of pollen from an anther to a stigma; effected by insects, birds, bats and the wind etc

The process by which pollen is transferred from an anther to the stigmatic surface of the pistil of a flower

Pollen transfer from anther to stigma

the transfer of pollen to a receptive stigma

The transfer of pollen from the anther to the stigma

Process necessary for the fertilization of a seed Pollen from the anther is transferred (by wind, rain, insects, or gardeners) to the pistil See also: cross-pollination, self-pollination

{i} process of fertilizing flowers and plants by transferring pollen to the stigma of a flower

the movement of pollen from a stamen to a pistil by pollinators (birds or insects)

The transfer of pollen from the anther of a stamen to the stigma of a pistil

- transfer of pollen from the stamens to the pistils of flowers

Transfer of pollen grains in seed plants from the stamens, where they form, to the pistil. Pollination is required for fertilization and the production of seeds. On the surface of the pistil the pollen grains germinate (see germination) and form pollen tubes that grow downward toward the ovules. During fertilization, a sperm cell in a pollen tube fuses with the egg cell of an ovule, giving rise to the plant embryo. The ovule then grows into a seed. Since the pollen-bearing parts of the stamens are rarely in direct contact with the pistil, plants commonly rely on external agents for pollen transport. Insects (especially bees) and wind are the most important pollinators; other agents include birds and a few mammals (notably certain bats). Water transport of pollen is rare. An egg may be fertilized by self-pollination (when the sperm comes from pollen produced by the same flower or by another flower on the same plant) or by cross-pollination (when the sperm comes from the pollen of a different plant)

transfer of pollen from anther to stigma

Fertilization of a flowering plant The transfer of pollen from the anthers of one flower to the stigma of that or another flower

the transfer of pollen from an anther to the stigma in angiosperms, or from the microsporangium to the micropyle in gymnosperms - pollination happens when pollen lands on a female part of a flower such as the stigma of a carpel Pollination can be caused by pollinators such as butterflies, bees, birds, bats but also by the wind or the water

transfer of pollen from the anther to the stigma of a plant

Process of transferring the pollen from its place of production to the place where the egg cell is produced This may be accomplished by the use of wind, water, insects, birds, bats, or other means Pollination is usually followed by fertilization, in which sperm are released from the pollen grain to unite with the egg cell

The transfer of pollen from the male part of flowers (the anthers) to the female part (a stigma) The transfer is accomplished by insects

the transfer of pollen from the male part of a flower (stamen) to the female part of a flower (the style and stigma)

Fertilization by the transfer of pollen from an anther to a stigma; effected by insects, birds, bats and the wind etc

The carrying of pollen from the male reproductive parts of the flower to the female reproductive parts Pollen contains male gametes When these male gametes come in contact with a suitable stigma, the ovule is fertilized to produce seed [16]
