NEETBotanyPhotosynthesis in Higher Plants
Match the historical milestones in the study of photosynthesis in Column-I with the year they were demonstrated or discovered in Column-II. Column-I Column-II (a) Role of air in the growth of green plants (i) 1882 (b) Discovered the release of oxygen (ii) 1854 (c) Evidence for the production of glucose in growing plants (iii) 1770 (d) T.W. Engelmann described the first action spectrum (iv) 1774 Choose the correct ans
Options
- A(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
- B(a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)
- C(a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
- D(a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
Correct answer
B. (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)
Step-by-step solution
The correct chronology is: Joseph Priestley showed the role of air in the growth of green plants in 1770 (a-iii); the release of oxygen in photosynthesis was linked with experiments around 1774 (b-iv); Julius von Sachs provided evidence for glucose production in 1854 (c-ii); and T.W. Engelmann described the first action spectrum of photosynthesis in 1882 (d-i). Hence the correct match is (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i).
