In this article we will discuss about the Mechanism of Mineral Salt in Xylem. After absorption from the soil by epiblema cells, the mineral salts pass radially inwards into the tracheary elements. With the transport of water the mineral salts also pass upwardly to reach the leaves and other parts. That xylem is the pathway for the transport of mineral [...]

In this article we will discuss about the Nitrogen Cycle. Nitrogen Cycle: Nitrogen is the fourth most prevalent element in living systems. It is a constituent of a number of organic compounds like amino acids, proteins, nucleotides, nucleic acid, hormones, chlorophyll, many vitamins, etc. However, its availability from soil is limited and even for that plants have to compete with [...]
