The technique of growing plants in nutrient solution WITHOUT soil is called:
AAeroponics (roots in misted air)
BHydroponics (roots in nutrient solution)
CAquaponics (with fish co-culture)
DMycorrhiza (fungal partnership)
Answer & Solution
Correct answer: B. Hydroponics (roots in nutrient solution)
HYDROPONICS = growing in nutrient solution without soil (Julius von Sachs, 1860). Aeroponics: roots in air + mist. Aquaponics combines hydroponics with aquaculture. Mycorrhiza is symbiosis with fungi.
