The given experimental set-up is used

Options

A. to show that `CO_(2)` is required during photosynthesis
B. to show that `O_(2)` is evolved during photosynthesis
C. for nutrients solution culture
D. to measure growth of a plant

Answer

C

Explanation

the given experimental set-up shows nutrient solution culture. in this typical solution culture technique, nutrient solution is placed in superior glass jars or polythene bottles covered with black paper (to prevent growth of algae and reaction of roots to sunlight). the jars contain split covers or corks with holes for suspending seedling, a funnel for adding solution and a bent tube for aeration, as shown in the given figure, regular aeration is required for proper growth and activities of roots.
