alleryThe 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.
