NEET Biology Mineral Nutrition In Plants Question Bank Mineral Absorption

  • question_answer
    If the amount of an ion absorbed by a root hair cell at \[0{}^\circ C\] is 5 gm and at \[20{}^\circ C\] is 20 gm. The amount of this ion absorbed actively should be

    A) 25 gm

    B) 20 gm

    C) 15 gm

    D) 5 gm

    Correct Answer: C

    Solution :

    At\[{{0}^{o}}C\], 5 gm ions are absorbed and at\[{{20}^{o}}C\], 20gm ions are absorbed. Energy is increased from\[{{0}^{o}}C\]to\[{{20}^{o}}C\], then the increase in ion absorption amount = 20 - 5 =15 gm.
