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 role of mineral elements in plants. The mineral elements, when present as ions or as constituents or organic molecules, perform several important functions in plants in a number of different ways (Table 9-3). They are important constituents of protoplasm and cell wall e.g., sulphur occurs in proteins, phosphorus in nucleoproteins and adenosine [...]
