They are not better they are different.
Cross-pollinated flowers usually have their stamens higher than their pistils. This is what will make it easer for the pollen grains to fall on the pistils for purposes of pollination
They will most likely have less because they are not the kind of flower that really sticks out because of certain coloring, so that's also why they can depend on wing more than animals to pollinate.
You can get the flowers, shrubs and fruit trees in your garden pollinated.
Hibiscus is actually pollinated by hummingbirds! Red flowers always most likely are because birds can see red better than insects (they're better at the blue and purple part of the spectrum). Also, the pollen is far away from the nectar. If a hummingbird puts its tongue into the flower, the pollen will be deposited on its back. An insect would never touch the pollen when crawling into the flower to the nectar. ^^
Flowers will not grow with soda better than they will with water. The sugar and carbonation in soda can kill flowers.
Some plants do not have flowers. Nearly all the plants you see around you are flowering plants: trees, bushes, vines, grasses and the "weeds". The flowers may not be big and showy, but they are there if you look for them. When flowering plants spread all over the world, about a hundred million years ago, they pushed aside the ferns and mosses and cone-bearing trees that had covered the planet for many millions of years. Of course, those plants are still here but they no longer have the planet to themselves as they did before the development of the super-successful flowering plants.
Common examples of anemophilous (wind-pollinated) plants are ragweed, grass, and conifers.(Generally, any pollen that is considered an allergen, comes from an anemophilous plant)
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.
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.
The anther makes the pollen I think, but you might wanna check though.
Any flower that is pollinated by an animal (not insect); pollinators include birds, bats, small mammals etc.
Because weeds are better adapted to grow than planted flowers.
