Statement A: In hydroponics or water culture, the nutrient solution must be adequately aerated to obtain the optimum growth of the plant.
Statement B: Root system of the plant requires proper amount of oxygen for respiration to release the energy required for active absorption of minerals of nutrient solution.
In hydroponics or water culture the roots system faces water oxygen deficiency as there are no pore spaces in nutrient solution. Since they do not get proper amount of oxygen, the active uptake of minerals by roots is hampered which results in poor growth. If aerated proper amount of oxygen is supplied to the root and adequate energy is formed in aerobic respiration and the roots can effectively absorb the minerals and utilize them in their metabolism and enhances the growth and development of plant.
