It is not necessary. Some flowers attract insect by their bright color as in case of Petunias.
A savanna does not have much insect pollinated plants e.g. colorful and scented flowers. Most of the time there are no flowers at all so don't be looking in the savanna for a bouquet.
Daisies, dandelions and roses are examples of plants that depend on insects for pollination. Grasses are an example of plants that depend on the wind for pollination. In grass, flowers are grouped together in twos and threes forming spikelets. The flowers are small but they have the same basic structure as an insect pollinated flower. They have ovaries, stigmas, stamens and petals. However, a dandelion is both a wind and insect pollinated flower, depending on its state.
Petals are both wind pollinated and insect pollinated, not one or the other. Insect pollinated petals are large and brightly colored while wind pollinated petals are small and brown or green in color.
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.
no some especially fragrant flowers are lantana- has a lemony smell and alyssum- really sweet floral
Some examples of insect-pollinated plants include sunflowers, lavender, roses, and fruit trees like apple and cherry. These plants rely on insects like bees, butterflies, and beetles to transfer pollen between flowers for reproduction.
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.
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.
The answer is really pretty simple. Flowers that are pollinated by insects are pollinated by insects going from one flower to an other, carrying pollen from one flower to the next. Wind pollination is caused by the wind carrying pollen from one flower to an other one.Usually insect pollinated flowers have large, brightly colored petals also sweet scented nectaries at the base of the petals - some flowers may look bland but when viewed under ultra violet or infrared light are very conspicuous.The Stamen is short, with anthers firmly attached inside the flower. The Stigma is sticky and is located on the inside of the flower. Additionally the pollen grain are produced in small amounts, it is rough/ spiky and its large. This features are used to attract insects for pollination. The pollen grains are sticky and rough so it clings onto the insect's body. The Stigma is also sticky so the pollen grains remains in place and wont get carried away by the wind currents.Many, but not all dicotyledonous flowers are insect pollinated.Wind pollinated flowers are small and inconspicuous. Sometimes green or brown in color and has no scent or nectaries (such as the flowers of grass plants).The Stamen has long filaments, with anthers that hang outside the flower. The Stigma is large, branched and feathery. The pollen grains are produced in large amounts, its smooth and light hence it can be carried away by the gentlest of wind currents.Many, but not all monocotyledonous flowers and cone producing gymnosperms are wind pollinated.
Yes. All flowers require pollinating to provide seed.
* petals with either bright colors or colors able to be seen by an insect's eye. * male and female parts on separate flowers.
All of them. Not all. Bess don't pollinate flour.
