Colourful petals. Plants that are not insect-pollinated are most often inconspicuous such as grass (which does have flowers!) or pines (which don't really have flowers but to produce massive amounts of pollen in spring, just because the wind is so random).
* petals with either bright colors or colors able to be seen by an insect's eye. * male and female parts on separate flowers.
No, the petals play a role in protecting the reproductive parts of the flower and attracting pollinators, but they are not directly involved in seed production. Removing the petals would not prevent the flower from producing seeds if the reproductive organs are still intact and able to be pollinated.
In a nut shell the reason is because of changing conditions. For example there is a flower that if very long and for an insect to be able to get to the nectur so the flower can reproduce the insect would have to have a very long "mouth" to reach the bottom of the flower. He predicted that such an insect exsisted and sure enough someone finally discovered the insect that drank from the flower about 20 years after his death, long "mouth" and all.
Depends on the definition of "closed flower".If you mean a flower that is enclosed with petals which are open, such as an Orchid, then the answer would be yes. This happens with many different types of flowers, some which have special adaptations to target a specific insect pollinator.If you mean a closed flower that has not yet opened, then the answer is almost definitely no. When the petals are closed and folded together the stigma and anthers are not yet mature; this means that even if an insect were able to get between the closed petals there sex organs of the flower would not yet be receptive to pollination.Generally insect pollination takes place in open flowers but there are specific cases of insect pollination in closed flowers as in case of many species of Ficus, Lotus etc.

Daisies are able to reproduce by sexual reproduction and asexual reproduction. They can also be pollinated by insects and animals.
Yes, If they did not they would not be pollinated; therefore, not being able to reproduce
No. Because without anthers, the pollen will not reach into the ovaries of the plant. Anthers are the male parts of the flower, and without them, a flower will not be able to develop into a fruit.
All plants have both a male part - the stamen - and a female part - the pistil. Therefore, all plants are able to take pollen from the stamen - which contains sperm - and use it to pollinate the eggs which are stored in part of the pistil. When the plant uses its own sperm to pollinate its own eggs, this is known as self pollination. However, suppose a bee or an insect lands on a flower and gets pollen on its feet. Then suppose that it lands on another flower. The pollen from the first flower will pollinate the eggs of the second flower. This is known as cross pollination, which the eggs of one plants are pollinated by pollen from a different plant.
If a plant doesn't get pollinated, it may not be able to produce fruits or seeds. This can result in reduced yield, poor crop quality, and ultimately affect the plant's ability to reproduce. Some plants may also exhibit abnormal growth or development if they are not pollinated.
Wind pollinated flowers sometimes look ugly because they don't need to attract bugs.
If a flowering plant is not pollinated, it will not be able to produce seeds. This means the plant will not be able to reproduce and create new plants. Pollination is essential for genetic diversity and the survival of many plant species.
