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 panegyric (US: / ˌ p æ n ɪ ˈ dʒ ɪ r ɪ k / or UK: / ˌ p æ n ɪ ˈ dʒ aɪ r ɪ k /) is a formal public speech or written verse, delivered in high praise of a person or thing. [1] The original panegyrics were speeches delivered at public events in ancient Athens.
Πανήγυρις is also transliterated as panegyry, [5] and in turn, some sources define panegyry to be a panegyric. [6] [7] A panegyric is a formal public speech ...
Non-vascular plants , with their different evolutionary background, tend to have separate terminology. Although plant morphology (the external form) is integrated with plant anatomy (the internal form), the former became the basis of the taxonomic description of plants that exists today, due to the few tools required to observe.

A nutrient cycle (or ecological recycling) is the movement and exchange of inorganic and organic matter back into the production of matter. Energy flow is a unidirectional and noncyclic pathway, whereas the movement of mineral nutrients is cyclic.

Knop's solution, which consists of his four-salt mixture and traces of an iron salt, [4] is still commonly used in plant biology today. [5] Dennis Robert Hoagland and Daniel Israel Arnon proposed that Sachs' solution (1860), Knop's solution (1865), Pfeffer's solution (1900), and Crone's solution (1902) [6] should be supplemented with boron ...
