What is the practical significance of studying the levels of organization of living matter?

The levels of organization of living matter is a symbol adopted to classify all living organisms on our planet. The wildlife of the Earth is truly diverse. Organisms can take various sizes: from simple and unicellular microbes, to multicellular creatures, and ending with the largest animals on earth – whales. Evolution on Earth took place in such a way that organisms developed from the simplest (in the literal sense) to more complex ones. So, either appearing or disappearing, new species improved in the course of evolution, taking on an increasingly bizarre appearance.
In order to systematize this incredible amount of living organisms, the organization levels of living matter were introduced. The fact is that, despite differences in appearance and structure, all living organisms have common features: they somehow consist of molecules, have repeating elements, in one sense or another – the general functions of organs; they feed, multiply, grow old and die. In other words, the properties of a living organism, despite external differences, are similar. Actually, focusing on these data, we can trace how evolution took place on our planet.
Depending on the level of organization of life, he is studied by a whole complex of scientific areas that are directly related to the person and the world that surrounds him, for example biochemistry, biophysics, molecular biology, molecular genetics, genetic engineering, cytology and others.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
