Leaves are the energy power plants of green plants and, along with the roots, are the most important nutritional organs. Like the eyes (summer and winter eyes), tendrils and inflorescences (shingles or later grapes), they form as lateral outgrowths on the nodes of young growing shoots. As the shoot tip grows in length, new leaves branch off continuously, which develop in a variety-specific way. With the help of leaf pigments such as chlorophylls, carotenoids and flavonoids, the light energy of the sun is absorbed by the leaves and converted into high-energy glucose (dextrose) and oxygen during photosynthesis using carbon dioxide and water. The carbon dioxide required for this is absorbed from the air through the stomata (stomata), usually on the undersides of the leaves. The oxygen produced during the day escapes through these small stomata
