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 .
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 ...
Many plants and animals have coevolved in such a way that the fruit is a good source of nutrition to the animal who then excretes the seeds some distance away, allowing greater dispersal. [59] Even seed predation can be mutually beneficial, as some seeds can survive the digestion process.

Phytochemicals are chemicals of plant origin. [1] Phytochemicals (from Greek phyto, meaning "plant") are chemicals produced by plants through primary or secondary metabolism. [2] [3] They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators. [2]
Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It provides organisms with nutrients , which can be metabolized to create energy and chemical structures.
In seed plants (gymnosperms and flowering plants), the sporophyte forms most of the visible plant, and the gametophyte is very small. Flowering plants reproduce sexually using flowers, which contain male and female parts: these may be within the same ( hermaphrodite ) flower, on different flowers on the same plant , or on different plants .
In plants, nutrient resorption is a process in which nutrients are withdrawn from senescing plant tissues. [1] It acts as a nutrient conservation mechanism. [2] It is influenced by several environmental and physiological processes.
