"Lenticel breakdown" is a global skin disorder of apples in which lenticels develop dark 1–8 mm diameter pits shortly after processing and packing. [ 18 ] [ 19 ] It is most common on the ' Gala ' ( Malus × domestica ) variety, particularly the ' Royal Gala ', and also occurs in ' Fuji ', ' Granny Smith ', ' Golden Delicious ', and 'Delicious ...
Selenium, which is an essential element for animals and prokaryotes and is a beneficial element for many plants, is the least-common of all the elements essential to life. [ 3 ] [ 63 ] Selenium acts as the catalytic center of several antioxidant enzymes, such as glutathione peroxidase , [ 11 ] and plays a wide variety of other biological roles .
Lenticel – One of the small, corky pores or narrow lines, on the surface of the stems of woody plants, that allow for the interchange of gases between the interior tissue and the surrounding air. Node – where leaves and buds are attached to the stem. Opposite – buds that are arranged in pairs on opposite sides of the branch

Each chemical element has a unique atomic number (Z— for "Zahl", German for "number") representing the number of protons in its nucleus. [4] Each distinct atomic number therefore corresponds to a class of atom: these classes are called the chemical elements. [5] The chemical elements are what the periodic table classifies and organizes.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
The term biometal can be used as a synonym to a metallic element that is involved in the function of a biomolecule, [16] hence also artificial systems can be considered when talking about biometals. Systems such as metalloproteins , metallopeptides and artificial metalloenzymes are examples of biomolecules containing metallic elements.
