Correct answer
C. Joseph Priestley in 1770 performed a series of experiments that revealed the essential role of air in the grow
Step-by-step solution
Joseph Priestley (1733-1804) in 1770 performed a series of experiments that revealed the essential role of air in the growth of green plants.Priestley, you may recall, discovered oxygen in1774. Priestley observed that a candle burning in a closed space – a bell jar, soon gets extinguished(Figure 11.1 a, b, c, d). Similarly, a mouse would soon suffocate in a closed space. He concluded that a burning candle or an animal that breathes the air,both somehow,damage the air. But when he placed a mint plant in the same bel
