The flower is a modified shorteneda shoot that is adapted to form spores, gametes (sex cells), and cross-pollination. After this process, seeds and fruits are formed. Flowers, the structure of which is quite simple, in biology a very interesting object of study.
Features of the structure
From the point of view of the scientific approach, each plantIs a whole system that exists by its own rules. The flowers have the following structure. The stem part of them is a combination of a pedicel and a flower-bud, on which leaves are located (they are scientifically called colorists). Colorologists include sepals, stamens and pistils, as well as petals. Most often these components are located around the center in several rows. If a plant has both stamens and pistils, they are called bisexual, or hermaphrodites. In the dioecious, there are either stamens (in this case a male flower) or pistils (a feminine version).
The perianth is another component thathave flowers. Its structure is such that it acts as a kind of protector of the plant and the main attracting pollinators. The perianth can be of different colors (in this case it is double), and can be painted in just one color - in this case they speak of a simple variety. The stamen, which is the male part of the plant, includes a filamentous filament and anther. In the very center of the flowers there is a pestle (there may be several of them, by the way). It consists of an ovary, a column and stigma. Features structure The flower is such that the stigma is involved in the release of a sticky liquid, through which pollen grains are captured and retained. Thus, each flower consists of:
Flowers, the structure of which can differ,vary depending on the number of parts, their location and shape. For example, plants that have stamens and a pestle at the same time are called bisexual. If there is either a stamen or a pestle, then the flower is scientifically called same sex. A plant can consist of several flowers, which are collected in inflorescences, and maybe even single. Of course, in the presence of inflorescences, it will quickly pollinate, while flowers will be less damaged as a result of the influence of unfavorable environmental factors. Inflorescences, in turn, can also be of two types: simple (the flower is located on the main axis) or complex (there are flowers of several orders).
Biology defines the structure of the flower as complexapparatus in which all its components participate at once. For example, when the pollen ripens, the anthers begin to burst, resulting in pollen on the stigma of the pistil. It is here that pollination takes place. By the way, it can occur cross-over, which occurs most often, but self-pollination sometimes occurs. The peculiarity of the cross method is that pollen is carried by wind, water, insects, birds and so on.
