The upcoming discussion will update you about the differences between Macro-Elements and Micro-Elements. Difference # Macro-Elements: 1. They occur in plants in easily detectable quantities. 2. The concentration of a macro-element per gm. of dry matter is at least 1 mg or 1000 µg/gm. of the dry matter. 3. They build up the plant body and different protoplasmic constituents. 4. [...]
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 [...]
