What are the different parts of the flower?
flowers allow the reproduction of some plants called angiosperms , so it is not surprising that botanists refer to different parts of the flower in terms of reproductive organs of men and women. There may be one or more pistins. This part of the flower resembles a bowling pin in the shape, with a rounded lower base is ovary . Inside the ovary there are reproductive cells or ovula . The coming from the ovary narrows into the neck called style and the button at the top of the neck is stigma . This part of the flower is sticky. When the pollen grains observe the stigma by fertilization or pollination from bee, wind or other means, pollen tubes grow inside style or neck and travel down to the burrows in the ovary or base. Here the sperm fertilizes egg or reproductive egg cells (singular egg). Eventually the egg develops on the seed.
Some plants may not rely on the chance of fertilization because also the contentThey provide different parts of the flower that consist of male reproductive organs. These organs produce pollen.
male reproductive system: rod is a part of a flower that looks like thin hair with follicle at the top. Usually there are several sticks surrounding the pistil. Hair is called fiber and follicle is anther where pollen is produced. The fiber and the ghost form a stick.
flowers that have both male and female reproductive organs are called Perfect flowers , while those with only one or the other are imperfect flowers .
In addition to the pistil (female organs) and sticks (male organs), the external faith is made of petals , while small, fine leaves at the base of the petals are separated . Together they are called Calyx . Under the chalice is a stem or SWRUNCLE .
flowers that have pistil, sticks, petals and sepala are called complete flowers . Flowers that lack one or more of these parts are called incomplete flowers .
flowers that rely on pollinators such as hummingbirds and bees usually produce nectar to attract them and bright colors to alert. Birds and bees have colorful vision and some flowers even have nectar guides - patterns that clearly appear in the range of ultraviolet, visible to bees, but not humans. When the hummingbirds reach deep into the flowering to get nectar, or when the bees explore flowers, pollen grains follow animals to be transferred to other flowers, and pollen from the petals are stored. Therefore, pollination occurs.
In addition to standard Blossom described above, there are other types of flowers such as composite flowers . Sunflowers and daisies are two common examples. CompositeThe sentences are thus named because they are actually the composition of dozens of small flowers - two types - which are organized to look like the only flower! The center of the sunflower or daisy is made up of miniature flowers wrapped side by side called disk flowers , while each petal of sunflower or daisies is rays flower. Together, the flowers of the beam and the disk form many common flowers. Alternately dandelions have heads that are made only from flowers of beams, while thistles have heads composed only of flowers of the disk.
