Explanation:
Detailed explanation-1: -Pollination by Wind Most species of conifers, and many angiosperms, such as grasses, maples and oaks, are pollinated by wind.
Detailed explanation-2: -Plants produce nectar to attract pollinators. As the pollinator moves from flower to flower collecting nectar, they are also moving pollen from flower to flower. Certain fruits and seeds will not be produced if their flowers are not pollinated.
Detailed explanation-3: -Effective pollination involves the transfer of pollen from the anthers to a stigma of the same species and subsequent germination and growth of the pollen tube to the micropyle of the ovule.
