After reading this article you will learn about the pathway of solutes from the external solution into the plant cells. Movement of low molecular weight solutes (e.g. ions, organic acids, amino acids, sugars) from the external solution into the cell walls of individual cells or roots (free space) is a non-metabolic, passive process, driven by diffusion or mass flow. Nevertheless, [...]
After reading this article you will learn about the passive and active transport of ions from the epidermis to xylem in plants. Passive Transport of Ions: Transport of ions from the epidermis to the xylem without any consumption of metabolic energy merely in consequence of the spontaneous disappearance of non-equilibria driven by a decrease in free enthalpy is known as [...]
After reading this article you will learn about nitrogen in relation to physiology, growth and response of crops. Nitrogen in Relation to Physiology of Plants Nitrate (NO3—N) and ammonium (NH4—N) are two major forms of inorganic nitrogen taken up by the plants. Most of the ammonium has to be incorporated into organic compounds in the plant roots, whereas nitrate is [...]
