Bright colours and nectar are features that attract insects who disperse the pollen from flower to flower.

The Flower:\nThe flower is the reproductive unit of some plants (angiosperms). Parts of the flower include petals, sepals, one or more carpels (the female reproductive organs), and stamens (the male reproductive organs). \nThe Female Reproductive Organs:\nThe pistil is the collective term for the carpel(s). Each carpel includes an ovary (where the ovules are produced; ovules are the female reproductive cells, the eggs), a style (a tube on top of the ovary), and a stigma (which receives the pollen during fertilization). \n\nThe Male Reproductive Organs:\nStamens are the male reproductive parts of flowers. A stamen consists of an anther (which produces pollen) and a filament. The pollen consists of the male reproductive cells; they fertilize ovules. \n\nFertilization:\nPollen must fertilize an ovule to produce a viable seed. This process is called pollination, and is often aided by animals like bees, which fly from flower to flower collecting sweet nectar. As they visit flowers, they spread pollen around, depositing it on some stigmas. After a male's pollen grains have landed on the stigma during fertilization, pollen tubes develop within the style, burrowing down to the ovary, where the sperm fertilizes an ovum (an egg cell), in the ovule. After fertilization, the ovule develops into a seed in the ovary. \n\nTypes of Flowers:\nSome flowers (called perfect flowers) have both male and female reproductive organs; some flowers (called imperfect flowers) have only male reproductive organs or only female reproductive organs. Some plants have both male and female flowers, while other have males on one plant and females on another. Complete flowers have stamens, a pistil, petals, and sepals. Incomplete flowers lack one of these parts. \n\nto find an extensive biology of plants please visit:\nhttp://users.pandora.be/educypedia/education/plantbiology.htm

Hi again, spiderlover!  Thanks for your vote for my best answer.  You are very welcome.\n\nMy favorite flower is a Lady's Slipper.  A number of them grow each spring between the horse's pasture and the woods, just over the stone wall.  They are fragile, look like orchids, and I believe they are protected.

In plain language such plants are called unisexual.\nNow let us go deeper than that.\n In Flowering plants, as far as the sex is concerned , there are the following possibilities.\n 1) The flower has both the sex organs,i.e. pollen producing stamens and ova/seeds producing carpels. \n   In such a case the flower is said to be BISEXUAL and the plant as a whole is called MONOECIOUS.\n 2) The flowers have either stamens OR carpels (Male OR     Female) ; but never both. In such a case the flowers are said to be Unisexual (male flower and Female flower.)\n  If both the kind develop on one and the same plant then the plant is still MONOECIOUS. Good example is common Corn or Maize plant. Another example is Coconut.\n  If flowers are unisexual and the male and female flowers develop on two DIFFERENT plants; Then the plants are said to be DIOECIOUS. Good examples are found in Cucumber family; Water melon , Cucumber , Different types of gourds etc.\n In Pinus Male and Female cones develop on the same tree.So it is MONOECIOUS and flowers UNISEXUAL.\n In Cycas unisexual flowers develop on two different trees so the tree is DIOECIOUS.\n Papaya is another example where the flowers are unisxual and the plant is DIOECIOUS.\n Kindly note that the Cotyledons have nothing to do with the sex of a plant/flower. The idea is absurd to say the least.

Flowers try to attract insects that will pollinate them.  They do this by being bright colors that insects will notice, and by having sweet smells that insects like.  Yellow is a common color for flowers because it is bright and easy for insects to see.

If you restrict this to botany, many people would say "orchids!!" This is because they are beautiful and have very intricate reproductive processes (often involving mimicry of female wasps or bees to induce males to try to mate with them, thus transfering pollen from flower to flower).\nSome others might nominate the sunflower or daisy family as the most highly evolved. The daisy-type flower itself is a very complex structure and takes a multitude of forms.

FLowers are the sex organs of the plant.  They are pollinated and make seeds.

It depends on the flower but they can attract moths, bees, beetles and bats. The reason for the scent is to attract the pollinator and the nectar is a reward for pollinating the flowers. Bee flowers are usually blue or yellow.

Flower petals are bright colors to attract bees and other insects. the bright colors lure the insect into the flower in which they pollinate the flowers. without the bright colors to attract the insects the flowers would have to seek other means to pollinate and reproduce.

The Magnolia flower has a number of features not found in many other flowers. Firstly the flower parts are in spirals not in whorls (rings). There are no green sepals just lots of white petal-like things (many more than the usual 3-5 that most flowering plants have), then lots of spirally-arranged stamens, then lots of free ovaries, also in a spiral. They are pollinated by beetles. Each ovary becomes a small fruit, with the entire fruiting structure somewhat cone-like. Each small fruit opens separately to release one seed. The seed has a fleshy coat called a sarcotesta.

When pollen fertilise with stigma, resulting in two seeds in the same fruit.

This requires a serious answer. I will not disappoint you .I will give a satisfactory answer after finishing my busy schedule to day only. Kindly look out for the 'Edit' in the answer.\n\nEDIT-: Cross breeding between two plants is possible and it is being practiced for many centuries. \nIt is more commonly called ‘Hybridization’ . This is usually undertaken to improve the quality of the plant concerned from man’s point of view.\n \nAll commercially important crops and fruits / flowers are the results of hybridization.\nUsually hybridization is successful between the two plants of the same species. \nTo put it in simple language ; It is possible between two rose plants but between rose (Rosa ) and Hibiscus not possible.\n It is possible between two varieties of wheat (Triticum ) ; but between wheat and rice ( Oryza ) is not possible.\n It is possible between two varieties of mango (Mangifera) ; but between mango and  orange ( Citrus ) is not possible. \n \nFor hybridization the  pollen grain are collected from one plant ( It is the donor ) and carefully dusted on the mature stigma of the other plant.( It is the recipient ). Now the cross fertilization takes place between the gametes of the two plants in side the ovary / ovule of the recipient. Donor plant has no further role to perform. \n The seeds are collected from the recipient and allowed to germinate to find the expression of the  desired character / s.\n\n The process described above is too simple but  in reality it is not so . It will require understanding of many botanical / scientific terms so I have avoided it.\n It is due to the practice of hybridization we can still feed the teeming population of the world. \n \nGrafting is NOT crossbreeding.

Various flowers which are scented with beautiful fragrance have essential oils in them.These are either secondary metabolites or they are present as an attracting substance in insect pollinating flowers.There are oil glands present inside the floral whorls strategically located near the stamens(male parts containing pollen) or near the ovary to facilitate pollination.The insects are directed by the aroma.

The Passion Flower is quite nice.  Orchids are pretty too.
