Characteristics of Nutrient Uptake
These results show certain characteristics of nutrient uptake.
- Selectivity: Certain mineral elements are taken up preferentially while others are discriminated against or nearly excluded.
- Accumulation: The concentration of mineral elements can be much higher in the plant sap than in external solution. This means the uptake is against concentration gradient.
- Genotype: Plant species differ genetically in nutrient uptake characteristics.
