In this ecology article, we will teach you a little more about the stamens, one of the most important parts of a flower when ensuring its reproduction. In addition to the definition we will try to show you what the stamens of a flower are for and why its function is so important. And, without them, we would be talking about a plant world very different from what we currently know.
Therefore, the purpose of this short article is to explain in a simple way everything you need to know about this part of flower plants and thus know a little better the plant world that surrounds us and that we must take care of, pamper and protect every day. So, continue reading to know better What are the stamens of a flower, its function and types.
What are the stamens of a flower
It is known as yarn to Flower male organ. This is presented as a small elongated strand, a modified sheet, which usually excels the center; It is here where is the ribs of the flower. In the same way, in the stamens it is where the pollen bags are located where it is where pollen occurs.
The set of stamens is called androecium. Androceo is one of the main parts of the male reproductive system of the vast majority of the plants of our planet. In fact, both in the case of gymnosperms, those that do not protect their seeds, and in angiesperms, which do protect the seeds and that usually have many more striking flowers.
The stamens are formed, mainly, by two structures:
The stamens filament
The filament is the sterile part of the yarn and is located just below the antera. Its function is mainly structural and in the vast majority of cases it usually has a cylindrical and fine form; Although there are species where they occur in the form of a sheet, more wide and thick. In other cases, yarn can also lack filament.
The anterior of the stamens
The antera is the fertile structure of yarn. This is, as we have commented, together with the filament. The way in which Antera binds to the filament varies according to the species. They are generally joined in their base or in the back of the filament. In addition, the antera is where the pollen sacks are located where, normally, there are no more than four sacks in antero.

What is the function of the stamens of a flower
The stamens function It is the reproduction of flower plants. Without them, the plants reproduction It would only be used using other methods such as children, stolons or cuttings. Here you can learn more about the reproduction of plants.
- The stamens are the organs that produce and contain pollenor the genetic information of a plant. Therefore, its purpose is to produce, store and help take this to the ovary of a female flower to guarantee the creation of the seed.
- One of its main functions is to get the attention of pollinating organisms. Therefore, they are usually quite striking as are the flower petals. However, this does not always have to be like this, or at least for the human eye, where it is sometimes difficult to identify. You can learn more about what are the pollinating insects and their importance here. In addition, some stamens also produce what is known as nectar. The nectar is a liquid solution, very rich in sugars, amino acids, mineral ions and other substances, attract animals to increase the success of flower pollination.
Types of flower stamers
There are several Types of stamens. We wanted to divide them into two large groups to facilitate their identification, but, in addition, we have added at the end of the article other possible variants.
Stamens connate or merged into the same spiral
- Within this classification we find the Monadelfothose that their filaments form a kind of beam and that are typical of the Myrtaceas family, to which eucalyptus belong.
- There are also Diadelfowhich are those stamens that are united among themselves for forming two beams. This type is very characteristic of the family of Fabaceas or commonly known as legumes.
- In addition, in the same classification of the connotes, we find the polyadelfoswhich are the stamens attached to each other for the filament and that form three or more do. It is characteristic of a large number of plants, among them we highlight those of the genus Citrus, such as orange and lemon.
- And finally, there are the stamens Sinantéreosthose whose forerasses are linked to a single body. This type of yarn is found above all in the Asteraceas family, where plants such as chamomile or sunflower are located.
DNAKED OR FUSED STAMES IN MORE THAN ONE SPIRAL
- Here we find the type stamens Epipétalowhere the filaments are united right at the base of the corolla. It is characteristic of many garden flowers such as those belonging to the primulaceas family.
- There are also the stamens Didinamo. Those that arise from the flower in two pairs and that one is more elongated than the other.
- Finally, within this group, we see the Tetradinamos which are those that present six stamens; two of them shorter than the rest.
Other types of stamens
Finally, we will talk about other types of stamens that can be divided according to their length, the so -called Exertsaccording to the position of the anteras, among which are the basifixes and dorsifijos, and even according to the dehiscence that marks how the tecas that produce the pollen of the flower are opened.
