Dominant Uptake Mechanism by Plant Roots
List-II (Dominant Uptake Mechanism by Plant Roots

|---|---|---|---|
| A | Nitrogen ($\text{NO}_3^-$) Nitrogen ($\text{NO}_3^-$) | I | Mass flow Mass flow |
| B | Phosphorus ($\text{H}_2\text{PO}_4^-$) Phosphorus ($\text{H}_2\text{PO}_4^-$) | II | Diffusion Diffusion |
| C | Potassium ($\text{K}^+$) Potassium ($\text{K}^+$) | III | Diffusion Diffusion |
| D | Calcium ($\text{Ca}^{2+}$) Calcium ($\text{Ca}^{2+}$) | IV | Mass flow and Root interception Mass flow and Root interception |
- Mechanisms of Plant Nutrient Transport to Root Surfaces (Barber's Concept):
- Nitrogen (Nitrate, $\text{NO}_3^-$): Highly soluble and non-adsorbed; transported almost entirely ($\gt 80\%$) via convective Mass flow $\rightarrow$ (I)
- Phosphorus (Orthophosphates, $\text{H}_2\text{PO}_4^-$): Strongly adsorbed and precipitated; transported almost exclusively ($\gt 90\%$) via Diffusion $\rightarrow$ (II)
- Potassium ($\text{K}^+$): Readily exchanged on clay edges; transported primarily ($70-80\%$) by Diffusion $\rightarrow$ (III)
- Calcium ($\text{Ca}^{2+}$): Present in high solution concentrations; supplied predominantly through Mass flow and Root interception $\rightarrow$ (IV)
- Systematic Match: (A)-(I), (B)-(II), (C)-(III), (D)-(IV) corresponds to Option 1.
Correct option: (1) (A) - (IN), (B) - (III), (C) - (IV), (D) - @),
