There is no fixed, commonly agreed upon system for classifying secondary metabolites. Based on their biosynthetic origins, plant secondary metabolites can be divided into three major groups: [2] Flavonoids and allied phenolic and polyphenolic compounds, Terpenoids, and; Nitrogen-containing alkaloids and sulphur-containing compounds.
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .
The word carminative is a derivative of Latin cārmen "card for wool", according to Hensley Wedgewood, on the humoral theory that carminatives "dilute and relax the gross humours from whence the wind arises, combing them out like the knots in wool".
Eating a diet high in fruits, vegetables, grains, legumes and plant-based beverages has long-term health benefits, [17] but there is no evidence that taking dietary supplements of non-nutrient phytochemicals extracted from plants similarly benefits health. [4]
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...

A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
