Answer
- Plants absorb minerals from the soil with their root system.
- Minerals are absorbed from the soil in the form of charged particles, positively charged cations and negatively charged anions.
- The absorption of minerals against the concentration gradient which requires expenditure of metabolic energy is called active absorption.
- The ATP energy derived from respiration in root cells is utilized for active absorption.
- Ions get accumulated in the root hair against the concentration gradient.
- These ions pass into cortical cells and finally reach xylem of roots.
- Along with the water these minerals are carried to other parts of plant.
