In the IUPAC system of nomenclature, groups are not considered as functional groups (which are indicated by secondary suffixes) but as substituents. Each such group (or substituent) is denoted by a secondary prefix. Some typical secondary prefixes are: ..

The normal process of growth that occurs in every plant body is known as primary growth. It is the result of the activity of primary meristem. The process of primary growth results in the formation of primary permanent tissues such as primary xylem, primary phloem and primary cortex. However in the..

Secondary xylem is the xylem that is formed during secondary growth. It is derivative of secondary meristem. It is a characteristic feature of only dicots. Secondary xylem is commonly known as wood. It is of commercial importance since it is extensively used..

Secondary axis is any other radial line passing through the centre of curvature other than the principal axis. ..

Secondary phloem is the phloem that is formed during secondary growth. It is a derivative of secondary meristem. Secondary phloem is characteristic feature of only dicots. It is also known as bast. It is also of commercial importance since it yields bast fib..

The organic materials that are biodegradable are treated with the help of decomposers and oxygen. Then, the water is also chlorinated to remove the germ..

In a dicot stem, secondary growth occurs both in the stele and cortex. The process occurs simultaneously but is caused by separate strips of secondary meristem. In the stele, secondary growth is initiated by vascular cambium, while in the cortex, it is initiated by cor..
