Hydroponics Setup—Technique, Scientist, Significance of Components, Applications
GeneralClass 12AllAnswered 27 Mar 2026
Answer
(i) Technique & Scientist:
The technique shown is Hydroponics (also called Solution Culture), first demonstrated by Julius von Sachs in 1860. This revolutionary technique enabled controlled studies of plant mineral nutrition.
(ii) Significance of Components:
Aerating Tube:
- Supplies oxygen to the nutrient solution
- Ensures roots obtain adequate O₂ for aerobic respiration
- Prevents root hypoxia and promotes optimal growth
Feeding Funnel:
- Allows replenishment of nutrient solution
- Essential as plants continuously absorb minerals, depleting the solution
- Enables precise control of nutrient concentrations
(iii) Commercial Applications:
- Tomato
- Seedless cucumber
- Lettuce
Hydroponics offers advantages like disease control, water efficiency, and year-round production in controlled environments.
