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.
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.
They need birds and insects to pollinate the trees. Plants that are not pollinated can't produce fruits or vegetables.
Colorful flowers are usually pollinated by attracting pollinators such as bees, butterflies, and birds with their bright petals and sweet nectar. These pollinators are drawn to the colors and scents of the flowers, and in the process of feeding on the nectar, they transfer pollen from one flower to another, aiding in the pollination process.
Any flower that is pollinated by an animal (not insect); pollinators include birds, bats, small mammals etc.
No, wind-pollinated flowers do not typically have large, showy flowers. Instead, they often have small, inconspicuous flowers that produce a lot of pollen to be carried by the wind to nearby flowers for pollination.
They can be pollinated artificialy or naturally (by bees or birds)
Because insects can see purple, blue etc. better than red, orange etc. That's why tropical red flowers are almost always pollinated by birds, and red berries are eaten by birds; birds can see red better, insects can see blue better. Insects are also quite good with ultraviolet light, which is why many flowers have markings that are invisible to us, but visible to them - they can see colours beyond our vision.
Not all flowers require insects for pollination.Most angiosperms (flowering plants), in particular dicotyledonous plants, require an agent of pollination; normally these are animals - mainly insects, but can also be birds, mamals, centipedes etc.Monocotyledonous angiosperms which comprose largely of grasses are pollinated mainly by wind.Gymnosperms (cone bearing plants) rely mainly on wind pollination and therefore produce large quanitites of pollen.
Showy flowers are typically pollinated by animals such as bees, butterflies, birds, or bats. These animals are attracted to the bright colors, strong scents, or sweet nectar of the flowers, and in the process of feeding, they unintentionally transfer pollen between flowers, leading to pollination.
A. Brightly colored flowers. In animal-pollinated plants, brightly colored flowers are common as they attract pollinators like bees, birds, and butterflies.
There are more than 2 flowers which are not colorful and showy. All anemophilous flowers (Flowers which are pollinated by wind) are such flowers as they have no need to attract insects or birds for pollination. Examples for such flowers are : Grass species, Coniferous trees (Pine trees), Ragweed flowers, Hickory family, the Hoary Plantain and Sweet Chestnuts.
