Welcome to the NCERT Solutions for Class 11th Biology - Chapter Mineral Nutirtion. This page offers a step-by-step solution to the specific question from Excercise ".$ex_no." , Question 2: why is purification of water and nutrient salts so....
Question 2
Why is purification of water and nutrient salts so important in studies involving mineral nutrition using hydroponics?
Answer
Hydroponics is the art of growing plants in a nutrient solution in the absence of soil. Since the plant roots are exposed to a limited amount of the solution, there are chances that the concentrations of oxygen and other minerals in the plant roots would reduce. Therefore, in studies involving mineral nutrition using hydroponics, purification of water and nutrient salts is essential so as to maintain an optimum growth of the plants.
