The collective name for the petals of a flower is the corolla .
My science book says... that the petal is used to attract pollinators. The purpose of petals is to attract insects or other animals to the flower. based of the information ab…ove i wrote down this answer and you all can write it down also OK here it is....... the purpose of the petals is to attract insects such as bees, and then the bees carry the pollen from the flower that attracted them to where ever the bees needed to go to.
The purpose of the petals is to attract animals to the flower so that they can distribute the its pollen to other flowers for fertilization and participate in pollination.
Depends entirely on the flower. Monocotyledonous flowers have floral parts in multiples of 3 - so they would have either 3, 6, 9 (etc.) petals. Dicotyledonous flowers ha…ve floral parts in multiples of 4 or 5 - so they could have 4, 8, 12, 16 (etc.), or 5, 10, 15 (etc.) petals.
No, the petals are the ones being protected. The sepals are the protectors.
There are several purple flowers with five petals including theCharming Centaury, Blue Phlox and wild geranium.
I'm not sure what you really mean by this question (is the plantone that does not produce petals? is the petal missing because itwas removed?) but it might help to think about… what function petalsplay in plants in order to get at some reasonable possibilities.Petals are typically a sort of advertisement or signal from theplant to animals that it is attracting for the purpose ofpollination. A plant with white petals, for example, might beattractive to pollinators that fly at dawn/dusk or night, becausethey can be seen more easily under darker conditions than otherflower colors. Flowers can also have nectar guides on them,sometimes even reflective in the UV spectrum and so seen by insectsbut not by us. They essentially can point to the source of nectar,orienting the insect to where to land for a quick, efficient meal(which also, for the plant, results in the insect landing the sameway on each flower, thus putting the pollen it collected on aprevious plant into the right position for getting that pollen ontothe female parts of the next plant). Petals can even make gettingto the nectar (or other) reward more difficult, making it difficultfor nectar theives to come in and get the reward withoutpollination. Once the petals have done thier job of attractingpollinators, and there is fertilization success, the petals canbecome a cue to the pollinators that "this plant has no morenectar", by changing shape or color. This signal makes it possiblefor the plant to stop making nectar in that flower, and thepollinator to move on to a different flower and not come to theconclusion that "this plant is not worth visiting", but instead,"this flower is not worth visiting". Usually, after successfulfertilization, the petal's job is done, and they fall off as thefruit develops. So, removing a petal from a plant before it ispollinated may make it less likely to get its eggs fertilized, butremoving it after might not make any difference at all, since thepetal's job is (typically) done.
Well, perhaps flowers of sulfur or frost flowers . But the presence of petals is part of the usual definition of a flower. There may be flowers without petals, but I can't …think of any. Glumiflorae flower has no petals. This family which includes grasses, sedges, rushes and cattails have very small, almost unnoticeable petals or no petals at all. The corn, rice, wheat, barley, and sugar-cane are included in this class of plants.
They are called pertunias :)
Flowers have petals to attract bees and birds to spread their pollen.
Simple: Naturally evolved roses usually have five petals. Domestic roses have additional petals that were bred from the stamens. Better: There are a over a hundred …species of roses in the genus Rosa. You can find exceptions to many of the general characteristics described. Exact numbers of petals, stamen and pistils, depends on the specie. (There are, in addition, an unknown number of cultivars.) Naturally evolved roses generally have five sepals, five petals and many spirally arranged stamens. The bases of the sepals, petals, and stamens are fused together to form a cup-like structure. Domestic roses have additional petals that were bred from the stamens. Roses have several to many pistils. It depends on the tye and variety.
The Corolla of a flower consists of petals.
