Many persons they do not know that plants, like the human beings and the animalsThey also have male and female reproductive organs. It is called pistil the organ that is usually located in the central part of the flowers and that corresponds to its feminine facet.
The pistil (a term that comes from the Latin word pistillum) is made up of ovaries, which house the ovules; the stigma that receives pollen with male gametes; and the style, which is the connector between the ovaries and the stigma. This last part, style, is not always present in plants.
The plants in which we can find the pistil are called angiosperm (whose scientific name is Angiospermae), although in everyday speech it is known as floral plants or plants with flowers. In short, they are spermatophytes (the vascular plants that generate seeds) whose flowers have ordered spirals or whorls of petals, sepals, carpels and stamens.
While the term petal is widely known, the remaining three belong to a more technical area, for which we will briefly define them below:
* the sepal is the part of the flower that shapes its calyx, its outermost set of leaves and which is usually green. The typical color of the petals, which are located on or inside the calyx, usually makes it go unnoticed;
* carpel is defined as a modified leaf that fulfills the female reproductive function in flowers;
* Finally, the stamen is the male organ that carries the pollen sacks, where the grains are produced. The term androecium refers to the set of stamens present in the same flower.
In the reproduction of pistil plants, the ovules that are enclosed in the ovaries are fertilized by the gametes present in the pollen. These male gametes are produced by the androecium, which is the male organ of the plant.
In other words, the pistil is the female region of the plant that is ready to receive pollen. Pollen is deposited on the stigma, which is found in the highest region of the pistil. Because of his viscous structure, pollen can stick easily.
The transfer of pollen to the ovules takes place in the so-called pollen tubes. These eggs can stick to the pollen tube inside the ovary or to the outer wall of the ovary.
In addition to the cavity formed by the carpels to house the ovules, there are also the loculi, which represent the seminal cavity, where the ovules are found that will be fertilized and, later, will become seed. In some cases, both the ovary and other complementary structures transform into a fruit after being fertilized. Another term that animals and plants have in common is placenta, which in this case is the inner surface of the ovary on which the ovaries are located.
In the same way that it happens with many other terms in the scientific field, today it is preferred gynoecium to pistil, since the latter is considered ancient. With respect to androeciumOn the other hand, it is the word that was used in the beginning and continues to be used today to give names to the male reproductive organs.
Pistil, in another sense, is the utensil used in the mortars to crush certain ingredients. Mortar is a bowl made of metal, stone or other material in which different kinds of solid substances are placed. What the pistil allows to do is to crush the solids to pulverize them or obtain another substance that they harbor in their inside.
