Wind pollinated flowers do not make nectar why?
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.
Why are wind pollinated flowers not usually brightly colored?
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.
On an island where there are no insects and birds the pawpaw plants produces only flower but no fruit?
They need birds and insects to pollinate the trees. Plants that are not pollinated can't produce fruits or vegetables.
Do wind pollinated flowers have large showy flowers?
No they don't, they usually don't have any coloured flowers because they don't need to attract birds or insects so pollination can take place and they don't have any nectar. hope this help :)
What flowers are pollinated?
Any flower that is pollinated by an animal (not insect); pollinators include birds, bats, small mammals etc.
What Two Ways Do Flowers Pollinate?
They can be pollinated artificialy or naturally (by bees or birds)
Why do bees like blue flowers most of all?
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.
Do flowers need insects to pollinate them?
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.
Which 2 flowers are not colorful and showy?
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.
Why is it that some plants have brightly colored flowers and other do not?
to attract bugs to land on it. After landing on the flower pollen will stick to the bugs feet, so then when the bug lands on another flower, it will pollinate it. That is one way of how flowers reproduce sexually.
Why do plants produce flowers?
To attract insects and birds
What percentage of food crops are pollinated by insects birds or mammals?
approximately 3/4 or 75%
