Some agents that help in pollination include bees, butterflies, birds, bats, and wind. These agents play a crucial role in transferring pollen between flowers, which is essential for the reproduction of many plant species.
True
Self pollination-The transfer of pollen from a male reproductive structure (an anther or male cone) to a female reproductive structure (a stigma or female cone) of the same plant or of the same flower.Self-pollination tends to decrease the genetic diversity (increase the number of homozygous individuals) in a population, and is much less common than cross-fertilization. Many species of plants have evolved mechanisms to promote cross-pollination and avoid self-pollination, though certain plants, such as the pea, regularly self-pollinate.Cross pollination-The transfer of pollen from the male reproductive organ (an anther or a male cone) of one plant to the female reproductive organ (a stigma or a female cone) of another plant.Most plants reproduce by cross-pollination, which increases the genetic diversity of a population (increases the number of heterozygous individuals). Mechanisms that promote cross-pollination include having male flowers on one plant and female flowers on another, having pollen mature before the stigmas on the same plant are chemically receptive to being pollinated, and having anatomical arrangements (such as stigmas that are taller than anthers) that make self-pollination less likely. Insects and wind are the main agents of cross-pollination.
Plants with separate male and female flowers play a crucial role in pollination because they rely on external agents, like insects or wind, to transfer pollen between the male and female flowers. This ensures genetic diversity and successful reproduction in the plant species.
The scent of flowers is felt due to diffusion hence insects which are agents of pollination are attracted by the
Agents Pollination are insects, birds, water and wind. They helps in Pollination transferring pollen grains from the anther of a stamen to the stigma of a carpel .
The primary agents of pollination for lotus flowers are insects, such as bees and beetles. These insects are attracted to the sweet scent and nectar of the lotus flower, and as they move between flowers to feed, they inadvertently transfer pollen from one flower to another, facilitating pollination. Additionally, some lotus species are also pollinated by wind.

are wind and water, insects, birds, and mammals.
In self-pollination, the reproductive structures of a plant, such as the stamen (male reproductive organ) and pistil (female reproductive organ), are involved in the transfer of pollen within the same flower or between flowers of the same plant. This process does not require external agents like insects or wind for pollination to occur.
Hi, they are pollinated by bees, Bye
insect vectors
they are agents of pollination.
