We want to continue increasing your knowledge in botany and helping you to know better the fascinating world of plants. Among the most important parts of the flower are The stamens or the androceo, which is the male reproductive system, whose function is to create what is known as pollen in order to ensure plant reproduction.
Discover here What is Androceo, its parts and its function. All the basic information you need to understand the importance of androceo or male verticiltypical of the phanerogamous plants, you will find it in this article of Ecology Verde.
What is Androceo and its characteristics
Androceo is called the Flower or stamente male organs set. Known within botany as male verticil It is responsible for the production of male gametes found among pollen grains. Generally, Androceo is besieged near the gynece or female reproductive system. Specifically in the perianto, which is nothing more than the set of floral leaves that offer subjection and protection of the flower.
There are, therefore, several Androceo types which are classified by how stamens occur in different species.
- Let’s bet: When the stamens are completely free to each other
- Fasciculate: When the stamens originate from the same point of union.
- Monodelfo: When the filaments are united by forming a layer that completely covers the style of the flower. This type of androceo is very characteristic in the Malváceas.
- Diadelfo: When the filaments are united in pairs. In this case, this type of androceo is typical of legume plants.
- SINANDRIA: When foreras and filaments are merged into a single compact structure. Typical of the cucurbitaceae.
- East: This type of androceo is very common in compounds. It is characterized by the united foreras while the filament remains free.
It is important to know that stamens are complex and diverse organs that have a short life. In addition, the androceo presents variations depending on the type of plant, being able to even merger with other parts of the flower as with the family of the Orchidaceae. In the same way, they also present different types of unions in order to favor the future reproduction of the plant.
In the Androceus there is also, in addition to pollenwhat is known as nectar. The nectar is a liquid solution very rich in sugars that fulfills the function of attracting animals to increase the possibilities of fertilization of the plant. We can say that, in addition to the attractive coloring of the petals, the stamens are another of the fundamental pieces for ensure optimal pollination of phanogamous plants.
To better learn this issue and its concepts, we encourage you to read these other articles about the reproduction of plants and verticos: what they are and what are the feminine (gynece) and the masculine (Androceo).
Parts of the androceo
Androceus is divided into two parts: the filament and the antera. Each of them forms what is known as the ribs or masculine organ of the flower. In fact, the Androceo is formed by a set of stamens or microphiles responsible for generating pollen.
Filament
The filament is a sterile structure by which a Union between the stem and the flower. Thanks to its epidermis rich in cutina it is easy to differentiate it from the rest of parts of the flower. Inside is a parenchyma or plant tissue through which a vascular beam circulates. In addition, the filament is the part of the androceo in charge of support and keep anteras. There are also flowers lacking filament.
Anther
Located in the upper end of the filamentthe antera is a fertile structure formed by Tecas. Las Tecas, made up of between two and four pollen bags, are in charge of produce pollen. Normally, the tecas are linked to each other by a connective tissue and both their coloration and their shape are very variable.
Once the male gametes have matured the antera opens to release the pollen and facilitate the reproduction of the plant. This phenomenon is known as dehiscence. Depending on how the opening of the antera occurs, we differentiate between longitudinal, transverse or poricidal dehiscence.
Functions of androceo
The main function of androceo is the production of male gametes that make up the Flower pollen. This process is carried out inside the pollen sacks located in the Antera in order to ensure the reproduction of the plant.
It is also responsible for give fastening and joining the stem with the rest of the flower parts. In addition, it gives additional protection to gynece or female reproductive organ.
In the same way, the Androceo is in charge of Call the attention of pollinators Thanks to the coloration and striking forms of the stamens, as well as through the production of nectar, which is able to attract and feed the animals responsible for helping during the pollination process.
Now that you have known much better the part called androceo of the flower plants, we recommend you read about the pollination process in this article about what pollination and its types are, as well as knowing more parts of the flower and its functions reading this other ecology article.
