They are known as verticilos to the whole of both Leaves, branches and flowers that are born at the same height, or from the same knot, with respect to the stem of the plant. These joint formations of the different organs of the plant have both structural and reproductive function, especially when we talk about floral verticos.
In this ecology article, we want to teach you a little more about the morphology of plants so that you increase your knowledge about botany. Join us a little more to know What are verticilos and which are the most important.
What are floral verticilos and leaves
Before starting to explain in depth what are the floral verticils it is important to know that, as we have pointed out in the introduction, other organs of the plants (such as the leaves or branches) also make up verticos.
Verticilated leaves
In this way, we can classify the plants according to the arrangement of their leaves: alternate leaves or those that are arranged around the stem and vertical leaves, those that are arranged in verticos or that They are born in the same knot.
Floral verticils
As for the flower, remember that it is the most characteristic reproductive structure of the phanerogamy plants. The flowers are formed by a set of modified leaves that originate once the plant has reached its adult stage and usually stand out for its coloration. Thus, we can distinguish main parts: peduncle, chalice, corola, androceo and gynece. All these structures that make up the flower are known as floral verticils.
Thus, as with the leaves, we can make a Classification of flowers according to their verticos:
- Acclamdeas: Those flowers without a perianto, also known as naked flowers.
- CLAMÍDEAS: Those flowers with perianto, also known as dressed flowers.
In turn, flowers are also distinguished from each other depending on the perianto of it. Remember that the perianto is called the set of floral wraps that protect the reproductive organs of the flower, that is, to the chalice and the corolla. Once that point understood, the flowers are divided into:
- Monoclammwhen they only have the chalice.
- Declamídeaswhen they have two verticos in the perianto.
- Homoclammideaswhen they have two similar verticos.
- Heteroclamídeaswhen both the corolla and the chalice are differentiated.
What are the floral verticilos and their parts
Next, we are going to talk about floral verticos or those structures that make up what is called as a flower. We will classify them into two groups:
- Androceo and gene: These two floral verticos may be alone or coexist.
- Chalice and corolla: These two foliace pieces make up what is known as perianto.
TOndroce
It is the Flower male sexual organ. It is formed by the stamens that, if time, have a filament with a closed sack just at the end that is called the Antera. The Antera is responsible for keeping the pollen. The stamens can occur both united and free and, in addition, grouped in different ways:
- Monadelfos stamensthose who are united by the filaments in a single beam.
- Diadelphs stamensthose who have two beams.
- Polyadelphic stamens Those who have more than two beams.
- Sygenic stamens Those who are united by the anteras in a single beam.
- Didinamos stamens formed by two long and two short stamens.
- Stamps tetradin formed by four long and two short stamens.
GINEECO
It is the female sexual organ where corpuscles are locked up whose function is to originate what we know as seeds. In the gynece, which is formed by capelos, are the ovary, style and stigma. This can be classified as
- Monocarpelar When it is constituted by a single carpel leaf that also welds on itself.
- Pluricarpelarwhen consisting of several carpelars. In this case they are also divided into two: syncárpicos, those that have welded carpels, and dialicarpelares, when carpels are free.
Chalice
The chalice is formed by the sepals, generally modified leaves of greenish color and performs a protective function. Depending on how the sepals are willing, we can differentiate them:
- Dialisepalowhen these are free.
- Gamosépalowhen they are soldiers.
Sepals can also be classified according to their duration in ephemeral or fleeting. That is, if this emerges when the flower is opened after fertilization or if it remains accompanying the fruit.
Corolla
The corolla is formed by the petals, which are modified leaves with attractive shapes and colors to achieve pollination. In the same way that happens with the chalice, it also differs in Dialipheals or gamopétala depending on the petals, free or soldiers respectively.
Other parts of the flower
Now that you know what verticos are and what they are, we will discover others Flower parts which are important to know:
- Peduncle: Peduncle is called the last part of the stem holding the flower. The peduncle is a thin pedicel that is responsible for joining flower to the stem. When the flower has it, it is classified as pedunculated flower. On the other hand, when it increases of it it is known as Sésil or sitting flower. It is usually green and cylindrical shape, as well as it can have varied sizes depending on the species.
- Receptacle: Also known as the floral axis, it is the widened part that follows the peduncle and where the rest of floral verticos settle. That is, the chalice, the corolla, the Androceus and the gynece.
