Currently, a biological system has become widespread, in which all living organisms are divided into five kingdoms: Bacteria, Protists, Mushrooms, Plants and Animals. At the same time, it is impossible to draw a sharp line between the individual kingdoms on only a few grounds. For example, representatives of the kingdoms of Mushrooms and Plants are characterized by similar symptoms. Only a deep analysis of the totality of characters, based on their origin, patterns of structure and activity, as well as a thorough study of the phylogenetic relationships between different groups of organisms, allows us to attribute a species or a larger taxon to a particular kingdom.
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.
