The endosperm is a tissue produced inside the seeds of most of the flowering plants following double fertilization. It is triploid (meaning three chromosome sets per nucleus) in most species, [1] which may be auxin-driven. [2] It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. This ...
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
The aleurone layer is the outermost layer of the endosperm, followed by the inner starchy endosperm. [1] This layer of cells is sometimes referred to as the peripheral endosperm. It lies between the pericarp and the hyaline layer of the endosperm. Unlike the cells of the starchy endosperm, aleurone cells remain alive at maturity.
Waxy endosperm is the counterpart in maize of the "glutinous" character in rice. [ 33 ] There is a wide range of species also presenting the waxy mutation, including rice, sorghum, millet, barley and wheat, which were characterised by starch granules staining red with iodine.
Macapuno also called coconut sport, is a naturally occurring coconut cultivar which has an abnormal development of the endosperm.The result of this abnormal development is a soft translucent jelly-like flesh that fills almost the entire central cavity of coconut seeds, with little to no coconut water.
In chemistry, congeners are chemical substances "related to each other by origin, structure, or function". [1] Common origin and structure.
This glossary is intended as introductory material for novices (for more specific and technical detail, see the article corresponding to each term). It has been designed as a companion to Glossary of genetics and evolutionary biology , which contains many overlapping and related terms; other related glossaries include Glossary of virology and ...
The suffix follows IUPAC nomenclature, and is mainly used in organic chemistry. However, inorganic compounds featuring unsaturation in the form of triple bonds may be denoted by substitutive nomenclature with the same methods used with alkynes , i.e., the name of the corresponding saturated hydride is modified by replacing the " -ane " ending ...
