The whorls are known as the set of both leaves, branches and flowers that are born at the same height, or from the same node, with respect to the stem of the plant. These joint formations of the different organs of the plant have both a structural and a reproductive function, especially when we talk about the flower whorls.
In this Green Ecologist article we want to teach you a little more about plant morphology so that you can increase your knowledge of botany. Join us a little more to know what are whorls and which are the most important.
Before beginning to explain in depth what flower whorls are, it is important to know that, as we have pointed out in the introduction, other organs of plants (such as leaves or branches) also make up whorls.
In this way, we can classify plants according to the arrangement of their leaves: alternate leaves or those that are arranged around the stem and whorled leaves, those that are arranged in whorls or that are born in the same knot.
As for the flower, remember that it is the most characteristic reproductive structure of phanerogam plants. The flowers are formed by a set of modified leaves that originate once the plant has reached its adult stage and that usually stand out for their coloration. Thus, we can distinguish some main parts: peduncle, calyx, corolla, androecium and gynoecium. All these structures that make up the flower are known as flower whorls.
Thus, as with the leaves, we can make a classification of flowers according to their whorls:
In turn, the flowers are also distinguished from each other depending on the perianth Of the same. Remember that perianth is called the set of floral envelopes that protect the reproductive organs of the flower, that is, the calyx and the corolla. Once that point is understood, the flowers are divided into:
Next, we are going to talk about the flower whorls or those structures that make up what is called a flower. We will classify them into two groups:
Is he flower male sex organ. It is formed by the stamens that, in turn, have a filament with a closed sac just at the end that is called the anther. The anther is responsible for storing pollen. The stamens can appear both united and free and, in addition, grouped in different ways:
Is he female sexual organ where some corpuscles whose function is to originate what we know as seeds are enclosed. In the gynoecium, which is made up of hairs, are the ovary, the style and the stigma. This can be classified into
The calyx is formed by the sepals, modified leaves generally greenish in color and performs a protective function. Depending on how the sepals are arranged, we can differentiate them:
Sepals can also be classified according to their duration as ephemeral or fleeting. That is, if it comes off when the flower opens after fertilization or if it remains with the fruit.
The corolla is formed by the petals, which are leaves modified with attractive shapes and colors to achieve pollination. In the same way that it happens with the chalice, it also differs in dialipet it or gamote it depending on how the petals are, free or welded respectively.
Now that you know what whorls are and what they are, let's discover other parts of the flower that are important to know:
