In order to know the meaning of the term gymnosperms, it is first necessary to discover its etymological origin. In this case, we can state that it derives from the Latin “gymnospermus” which, in turn, derives from the Greek. Specifically, it is the result of the sum of two Greek words:
-The term “gymnos”, which can be translated as “naked”.
-The noun “sperma”, which is equivalent to “seed” or “semen”.
The idea in question refers to a specific type of plant.
Gymnosperms are plants belonging to the set of phanerogams that present their seeds uncovered, since their carpels are not constituted as closed cavities that enclose the ovules. The firs and the araucarias, for example, are gymnosperm plants.
It is important to stop at the given definition of gymnosperms to understand precisely what it refers to. Is named phanerogam to the plant whose reproductive organs can be seen in the form of flower. In the flower, fertilization takes place, which allows the development of the seeds with the embryos of the new specimens. Carpels, on the other hand, are transformed leaves that form a pistil (the female organ of vegetables).
Returning to the idea of gymnosperm, therefore, it is a plant with flowers and open carpels that leave the seeds at Discover. Different is the case of angiosperms, which develop fruits that contain the seeds inside.
The reproduction of gymnosperms is slow. It may take a year from pollination to fertilization, and then another three years for seed to mature. Most gymnosperms, on the other hand, are pollinated through the action of the wind.
Other information of interest about gymnosperms are the following:
-Except for some exceptions, they are evergreen plants.
-The usual thing is that they have female and male sporophytes located in themselves, that is, they are monoecious.
-They have been dated in the so-called Carboniferous period.
-Although it is true that they can be found in any corner of the planet, the fact that, as a general rule, they exist, above all, in arctic areas and very cold climates is no less true.
-They have the peculiarity that they are very tall and that they have a very long life.
-In the same way, it is important to note that some of the gymnosperms are highly recognized and praised for the quality of wood they offer.
-At present it is estimated that there are more than 1,000 species of gymnosperms and these, in turn, can be classified into 88 different genera.
-Among the best known gymnosperms we can highlight some such as cedar, juniper, pine, cypress, redwood, ginkgo biloba … However, we must not forget about cycadophites or gnetophites either.
