To know, grow and appreciate plants and flowers it is necessary to know how they work in their biological system. Botany is a discipline of biology and is the science studying plants life. Its name derives from the Greek “botane” which means pasture, grass or fodder. The very beginning of botany as a science is the classification system of plants species and because of the great diversity in the plant kingdom, it is a branched out science including different disciplines such as structure, growth, reproduction, metabolism, development, diseases, chemical properties and evolutionary relationship among taxonomic groups. Some important branches are plant anatomy, carphology, dendrology, phytogeography and so on. In this section you can find information to deepen your knowledge on crucial elements marking every plants life.Botany is specialized in everything concerning plants vital as we said before. What we are going to talk about in this section exactly concerns chemical elements considered crucial for every plant’s life. Nitrogen, ... continua

, for example, is the most important nutritive element for plants because it is necessary for producing proteins and nucleic acid. Another important nutritive element is potassium. The one used by plants is the soluble potassium found in the circulating solution contained in the soil. Potassium is an important element for the right plants growth because it is the crucial factor for many biological process. Phosphorus is a crucial element for ornamental and flowering plants because affects flowers, buds structure and roots development. Iron is considered among the ten essential elements for a plant’s life. Leaves are the plants elements where iron is mainly contained that’s why, being so linked to chlorophyll, when there is a lack of iron plants lose their bright green leaves. The first scientist who studied the plant kingdom was Theophrastus whose most important books are two large botanical treaties: “Enquiry into plants” and “On the causes of plants”. In his works he explained over five hundred plants composition and use in medicine. Soon after the classification system bestowed botanic the science rank, a step ahead in classification system was taken by Carl Linnaeus who with his manuscript “Systema Naturae” dictated rigorous criteria for classification in animal, plant and mineral kingdom. Another important work by Linnaeus was “Philosophia botanica” a book containing a complete survey of the taxonomy system used in his earliest works. In this manuscript he divided plant kingdom into varieties, species, genus, order and classes.
