What is flowers?
Flowers are modified stems and leaves. This modification caused by the resulting number of enzymes that are stimulated by a number of specific phyto ¬ hormones. The formation of flowers with tightly controlled genetically and in many types of environmental changes induced by specific, such as low temperature, duration of lighting, and water availability (see article flower formation).
Flowers nearly always symmetrical shape, which can often be used as the character of a taxon. There are two forms of interest based on the symmetry of its form: aktinomorf ("star-shaped, radial symmetry) and zigomorf (mirror symmetry). Forms aktinomorf more prevalent.
Religiosa Crateva flowering plants perfect: have stamen and pistillum.
Flowers called the perfect flower if you have the appliance male (stamens) and female tool (pistil) together in a single organ. Such interest is called a sissy or hermaphrodite flowers. An interest is said to flower in full when it has all the main sections of interest. Four main sections of interest (from outside to inside) is as follows:

• flower petals or calyx;
• Crown interest or a Corolla which is usually thin and can be colored to attract insects that help the process of pollination;
• male genitalia or androecium (from the Greek Andros oikia: home for men) form the stamens;
• female genitalia or gynoecium (from Greek gynaikos oikia: "house woman") in the form of stigma.
Female reproductive organ is the fruit or leaf at its base carpellum that there would be fruit (ovary) with one or a number of ovule (ovulum, plural ovules) which brings the female gametes) inside the embryo sac. At the end there is the stigma of the pistil or stigma to receive pollen or pollen. Pistil stalk or the stylus acts as a way for the pollen to the ovary would be.
Although the structure of interest described above as the structure of plants, which is said to "general", plant species show a great variety of modifications. This modification is used botanical to make connections between plants with one another. For example, two subclasses of flowering plants are distinguished from the number of organs of the flowers: dicotyledonous plants typically have 4 or 5 organs (or multiples of 4 or 5) while the monocot plant has three organs or multiple.
Interest Function
Biological function as a vessel of interest is union of male gametes (microspores) and female (makrospora) to produce seeds. The process begins with pollination, is followed by fertilization, and continues with the formation of seeds.
Some flowers have a bright color and ecologically functioning as a decoy animal pollination helpers. Some other flowers that produce heat or special perfume, as well as to entice animals to help pollination.
Human long been captivated by the flowers, especially colorful. Flowers become one of determining the value of a plant as an ornamental plant.
