Many people have heard the term "morphological signs" in the lessons of the Russian language.
But not everyone knows that we can apply it to biology.
To understand what signs of living organisms should be attributed to morphological, it is first necessary to determine the terms.
Morphological signs of plants and animals
So, let's start from the very beginning. Science morphology studies the external and internal structure of living organisms or their groups (genera, species, orders). There are external and internal morphological signs of living organisms. Internal morphology is a well-known anatomy. Do not also confuse morphology with physiology, which deals with the study of the functions of certain organs or systems of animals or plants.
It seems that in the definition of morphology there is nothingComplicated. But behind the apparent simplicity lies a huge amount of information. The morphology of animals combines several sciences at once: anatomy, histology, cytology and embryology. The same is true with the morphology of plants. It is for a number of morphological characters that we can refer the animal to this or that species, genus, or even a detachment. This, for example, the height at the withers, weight, color of the coat and eyes, the length and shape of the tail, as well as other features of the structure.
The morphological features of plants include the shape and size of the leaves, the shape of the stem, the type of flower and fetus, and the like.
Like any living object, a person tooObeys the general laws of biology. And in anthropology (a science that studies man) there is a special subsection devoted to the morphology of man. This science is tightly connected with racial science and is engaged in studying certain patterns of development and changes in certain characteristics characteristic of different people. For example, the morphology of a person can explain how the skull of a Negro differs from a European skull or reveal the patterns of skin and hair color changes depending on the habitat of groups of people. Returning to the morphological features, it can be said quite simply: this is how you look - your height, hair and eye color, skin tone and body constitution.
Morphological signs of the soil
There is a widespread classification of soils,It is also based precisely on their morphological features. Do not be surprised, because each type of soil can be described, based on its external characteristics. In this case, scientists take as a basis such morphological features as the structure, thickness of the soil layer and its individual horizons, color, structure, composition, neoplasms, inclusions. And because the processes taking place in the soils have a direct effect on all the listed features, studying the morphology of the soil, one can learn a lot about its origin and history.
