There are terms whose definition is implicit in the word itself. This is the case of sunflower , where it is easy to detect the presence of the verb rotate (to go around, move around an axis or point) and the noun sun (the luminous star that is located in the center of the solar system, of which it is a part. the Earth ).
A sunflower is a plant that, as its name suggests, performs heliotropism : a movement towards the sun. In this case, the flower of the plant modifies its position to face the sun's rays.
Also called mirasol , the sunflower demonstrates positive phototropism since the tropism (movement to orient itself) of its flower is generated by light and is carried out, precisely, towards the light. When the orientation is opposite to the illumination source, it is called negative phototropism .
It is important to mention that sunflower heliotropism manifests itself while the plant is young. After maturity , the flower stops rotating and adopts a stable position facing east.
Helianthus annuus is the scientific name of the sunflower, a species native to the American continent that has a herbaceous stem capable of reaching a height of about two meters. The leaves of the sunflower are heart-shaped and petiolate, while its flowers have a yellowish color.
In addition to everything indicated, we cannot ignore that several of these plants are the protagonists of one of the most relevant paintings in history. We are referring to "The Sunflowers", which was painted in 1888 by the Dutch artist Vincent Van Gogh. However, it must be said that this work is part of a series by the same painter and has the same title as her.
In the same way, we cannot ignore the existence of a book of stories from 2004 entitled "The Blind Sunflowers" and which was written by the writer Alberto Méndez. The Spanish Civil War is the theme of this work, which is made up of four works: "The blind sunflowers", "If the heart thought it would stop beating", "The language of the dead" and "Manuscript found in oblivion".
It is important to note that the sunflower is cultivated on a large scale to take advantage of its seeds , which are edible and used to make oil.
As a food, sunflower seeds are popularly known as sunflower seeds . Typically, the seeds are roasted and then salted. Sunflower oil , meanwhile, is obtained by pressing the seeds.
More and more people are choosing to consume sunflower seeds. This is because they are considered to provide many benefits to the body such as controlling weight, improving the condition of the skin, increasing hair health and even combating fungal infections.
In the same way, we cannot ignore that they are considered to help improve mood, that they are useful in fighting infertility problems in men and that they help to sleep better. Advantages to which we must add that they serve to reduce the risks of suffering from Parkinson's, that they strengthen bones and that are useful for improving cardiovascular health.
