Q. Why all the minerals present in soil can not be passively absorbed by roots?
A) Mineral existence as ions is more than absorption
B) Due to less concentration of ion in root interior than soil
C) Due to more concentration of ions in root interior than in soil
D) None of the above
Explanation
Mineral exists in soil as ions which are generally absorbed from the soil by both active and passive transport. Because sometimes concentration of ions in soil is 100 times more as compared to concentration in root system in its interior. So, all mineral cannot be absorbed passively
