Pestle is what? Detailed analysis of the structure and purpose of the pestle

The flower is the most amazing part of most representatives of the flora, possessing various forms of form, flavor and color. But how does it happen that flowers reproduce? Each flower has stamens and a pestle - it's its reproductive organs.

What does the pestle consist of?

Pestle is an element of bud, consisting of many carpels. Some plant species may have more than one pestle, and 2 or more.

The lower part of it is usually swollen, dense and is called the ovary, which gradually turns into a narrower column and stigma. There are also species, for example, poppies, in which the column in the pistil is absent, and the ovary immediately passes into the stigma. The upper part of the pistil is designed to catch pollen during pollination, so the shape of the stigma is different - stellate, filiform, lobate, pinnate. The height of the column depends on the ability of the stigma to recognize and capture the pollen grains.

Where do the seeds come from?

Pestle is the storehouse of seeds. Future seeds in the form of ovules are stored in the ovary of the pistil. In the process of pollination pollen moves along the column deep into the ovary, seeds are formed, and the ovary itself becomes a fruit. That is why it is considered the most important part of the flower.
All flowers are divided into bisexual, same-sex women and same-sex men. Row, pea and cherry are included in the family of bisexuals. Same-sex female plants in the bud lack stamens, and in same-sexed males have pestles. Among gay, you can meet a cucumber, sea buckthorn, poplar. The flowers of these plants can be partly male and partly female.

How are the flowers pollinated?

If with bisexual plants everything is clear, they multiply in the process of self-pollination, then with same-sex all is much more complicated. More often male and female buds grow on one plant (tree, shrub). Without the help of insects, the pollen is transferred from the male flowers to the female pestle. This is a pumpkin culture, hazel and cucumber. Dioecious are those plants in which shrubs with male and female flowers grow separately. Most of them are representatives of the urban flora (aspen, poplar, nettle, dandelion and willow).

Answering the question: "Pestle is that: the vital organ of the flower or the accompanying element of the evolutionary process?", It can be concluded that without a pistil, pollination in principle is impossible. But the evolutionary division of plants into males and females brings certain inconveniences to a person's life, for example with poplar fluff - with his help seeds from a man's tree fall on the seeds of a woman.
