Q. Select the correct sequence of experiments that led to a gradual understanding of photosynthesis in green plants.
A) Production of glucose → role of air → release of oxygen → absorption spectra of chlorophyll a and b
B) Absorption spectra of chlorophyll a and b → production of glucose → release of oxygen → role of air
C) Role of air → release of oxygen → production of glucose → absorption spectra of chlorophyll a and b
D) Release of oxygen → production of glucose → absorption spectra of chlorophyll a and b → role of air
Explanation
[Solution from source] Priestley (1770) showed the role of air; Ingenhousz showed green parts release oxygen in sunlight; Sachs (1854) showed glucose is produced and stored as starch; Engelmann later related light absorption by chlorophyll a and b to photosynthesis. Answer (3).
