Explain the active absorption of
minerals.
Answers
Answer:
Active mineral absorption is an active process and thus it requires the expenditure of metabolic energy (ATP). Active mineral absorption can occur both along and against the concentration gradient by osmosis or through special carrier proteins in the plasma membrane.
Answer:
(1) Plants absorb minerals from the soil with their root system.
(2) Minerals are absorbed from the soil in the form of charged particles, positively charged cations and negatively charged anions.
(3) The absorption of minerals against the concentration gradient which requires expenditure of metabolic energy is called active absorption.
(4) The ATP energy derived from respiradon in root cells is utilized for active absorption.
(5) lons get accumulated in the root hair against the concentration gradient.
(6) These ions pass into cortical cells and finally reach xylem of roots.
(7) along with the water these minerals are carried to other parts of plant.
