The female reproductive organ of plants is called Gynece in biology. It is one of the most important parts of a flower that we have decided, here in ecology, explain and clarify questions such as What is gynece, what are its parts and what is its functionas well as some of its main characteristics. Again, as in other articles, we want to get a little closer to the world of plants to increase your knowledge in botany. Knowing the parts of a flower, such as gynece and Androceo, will help you not only enrich your basic knowledge, but to understand the complex world you have around you. And do not worry if first it seems very complicated, you just need to get comfortable and read this simple article echo for all lovers of the natural world.
What is gynece
It is called gynece, formerly called pistilto the set of Flower female organs. Located in the center, the flower gynece is composed of one or more modified leaves that take the name of carpels. Carpelos are those specialized floral verticos in the production of female ovules or gametes. In fact, gynece varies depending on the type of classification within the kingdom of plants.
In the case of angiosperms plants, carpels are merged to create a structure that protects ovary to favor the production and development of ovules. However, in the case of gymnosperms plants the carpels of the plants are free and open so that the ovules are without any protection. Taking into account these differences we can start talking in depth of the gynece parts so you can learn to differentiate them.
Gynece parts
Next, we explain in a clear and simple way what are the parts that make up the gynece and how they form or why each of these structures that make up the organs of the female reproductive system of the flowers are formed:
Stigma
It is located at the top of a carpel or, in the case of angiosperms, in the upper area of the carpels.
Style
It is formed by a folding of carpel itself or by the union of several carpels. Some plant species have a styleless gynece.
Ovary
The ovary is formed by a widened portion at the base of a single carpel or as a result of several fused carpels. In addition, depending on their location, the ovaries are classified in Supero, if it is located in the floral, semi -inferous receptacle if it is besieged in an intermediate and ínfero position is inside the floral receptacle. In the same way, they are also classified depending on the number of carpels that form it. We will talk about a unicarpelar ovary when it is constituted by a single carpel capable of folding to give protection to ovules, bicarpelar when they form two carpels and multicarpe or multicarpelar, if it is formed by a fusion of several carpels.
They can also be classified depending on the number of ovules inside. Here we will talk, as is the case with the carpels of: uniovular, with the only ovule, biovular, with two ovules inside and multivular with several ovules.
Gynece function
Gynece has as its function the production and protection of female sexual ovules or gametesin order to ensure the pollination process that will result in the Seed creation. In addition, it also facilitates the reproduction and dispersion of the seeds in order to ensure the survival of the species.
Each part that forms the gynece is responsible for fulfilling a vital function to achieve the planting of the plant. Therefore, we will explain the function that each of these parties performs separately:
Stigma
The stigma has as its main function to receive pollen grains or male gametes. Therefore, it is impregnated with a sticky substance to ensure that the pollen does not dispense.
Style
This tubular shape structure, whose length varies depending on the species, is responsible for joining the stigma with the ovule. In this way, when the pollen grain is attached to stigma, the germina style in order to create a pollen tube so that it reaches the ovary.
Ovary
The ovary is the cavity formed by a single or several carpels where fertilization occurs. Once pollINED, the ovary grows until the seed is protected into the interior. However, the main function of the fruit will be to ensure the dispersion of the plant. Hence, many fruits we know are fleshy to attract animals that will be in charge of transporting the seeds and dispersing them passively through the feces. They can also count on structures capable of easily adhering to animals or, simply, facilitate their dispersion by other climatic agents, especially, thanks to the wind as it happens with the samaras.
