Photosynthesis in Higher PlantsMedium
Question
Select the correct sequence of experiments that led to a gradual understanding of photosynthesis in green plants.
Options
A.Release of oxygen → production of glucose → absorption spectra of chlorophyll a and b → role of air
B.Production of glucose → role of air → release of oxygen → absorption spectra of chlorophyll a and b
C.Absorption spectra of chlorophyll a and b → production of glucose → release of oxygen → role of air
D.Role of air → release of oxygen → production of glucose → absorption spectra of chlorophyll a and b
Solution
Sol. [Key Concept: Historical sequence of DNA experiments]
Following is the appropriate sequence of experiments that led to a gradual understanding of photosynthesis in green plants.
Role of air in Glucose (Joseph Priestley's bell jar experiment) 1770
↓
Release of oxygen (Jan Ingenhousz's experiment using aquatic plant)
↓
Production of Glucose (Julius Von Sach's experiment) 1854
↓
Absorption spectra of chlorophyll a and b (T.W. Engelmann's experiment)
