wind pollinated
The pride o barbados is insect pollinated because it produces sweet nectar and is brightly coloured which attracts insects.
Nectar is produced by flowers to attract insects, bats or birds that will help to carry its pollen to other plants (and bring fresh pollen to it). If a plant is pollinated in the wind, then it doesn't need to spend the energy to make nectar.
It's bright and showy, and even has little nectar ducts under its petals, so insect-pollinated. Wind-pollinated plants generally don't have flowers, or the flowers are very small and inconspicuous, like those of grass. Wind-pollinated plants also make far more pollen (try tapping a pine tree or reed in spring) because the wind does not take it directly to its destination, much of it will be lost. With insects there's a fair chance the little there is will reach another flower of the same species.
Hibiscus flowers are primarily insect-pollinated, relying on bees, butterflies, and other insects to transfer pollen between flowers for successful pollination. This is due to the structure of the flower, which is designed to attract and accommodate specific pollinators.
Insect-pollinated flowers are often brightly colored, have nectar guides or fragrances to attract insects, and have sticky pollen grains that adhere to insects for transfer. Water-pollinated flowers are often dull in color, lack nectar or fragrance, and produce large quantities of light, buoyant pollen grains that can be carried through water currents for dispersal. Additionally, water-pollinated flowers tend to have feathery stigmas that can easily capture pollen carried by water.
Wind-pollinated flowers tend to be less showy and colorful compared to insect-pollinated flowers which are often brightly colored and fragrant to attract insects. However, the structure of wind-pollinated flowers is specialized for efficient wind dispersal of pollen, which is important for their reproduction. So, while they may not be as visually attractive to us, they are still well-adapted for their method of pollination.
Wind-pollinated flowers have many key differences from insect-pollinated ones. Since they don't need to attract insects, wind-pollinated flowers tend to have smaller petals, are odorless, are less colorful, and don't have nectar. Examples are ragweed, corn and wheat.
insect pollinated
Wind-pollinated plants do not need colorful flowers as they are not pollinated by animals, insects or birds. Since wind-pollinated plants do not need colorful flowers, they might as well put their energy into making their pollen lighter, or more of it.
Insect-pollinated flowers may still be pollinated by wind as a backup method to ensure successful pollination in case insect activity is limited. Wind can help transfer pollen between flowers when insects are scarce or when weather conditions are unfavorable for insect pollination. This redundancy increases the chances of successful pollination and seed production for the plant.
Roses are pollinated by insects such as bees and butterflies, though they can also be pollinated by the wind. Honeybees are the most common pollinators of sunflowers, and daisies are also pollinated by bees.
