6. Spraying sugarcane crop with gibberellins increases the length of the stem, thus increasing the yield by as much as 20 tonnes per acre.

7. When glyceraldehyde-3-phosphate is converted to 1,3 bisphosphoglyceric acid in glycolysis, the process is coupled with ATP utilisation.

8. In glycolysis, 2 phosphoglyceric acid is converted to phosphoenolpyruvate which is coupled with NADH utilisation.

9. Malic acid → OAA, does not couple with the NADH production.

10. Malic acid → OAA, does not couple with the CO₂ release.

11. There are diverse groups of PGRs in plants, principally belonging to five groups: auxins, gibberellins, cytokinins, abscisic acid and ethylene.

12. Splitting of the water molecule takes place on the beneath the chloroplast inner membrane.

13. In photosynthesis, protons accumulate in the intermembrane space of the mitochondria when electrons move through the ETS.

14. Cytokinins is an example of intrinsic factor that affects the development of a plant.

15. During photosynthesis CO₂ from the atmosphere is taken in by leaves through stomata and used for making carbohydrates, principally glucose and starch.

16. Development in plants (i.e., both growth and differentiation) is under the control of extrinsic factors.

17. Isocitric acid → α-ketoglutaric acid, does not couple with the O₂ release.

18. Nutrients is an example of extrinsic factor that affects the development of a plant.

19. Lipids are oxidised to release energy.

20. OAA + acetyl CoA → citric acid, does not couple with the GTP production.

21. Not all GAs are having pH less than 7.

22. In C₃ plants the primary O₂ acceptor is PGA.

23. PGRs may act synergistically or antagonistically.

24. Succinyl-CoA → succinate, does not couple with the FADH₂ production.

25. Fumarate → malate, coupled with the NADH production.

26. In glycolysis, Glucose is converted to glucose 6 phosphate which is do not coupled with ATP utilisation.

27. On splitting Fructose 1,6 bisphosphate into glyceraldehyde-3-phosphate and Dihydroxy acetone phosphate in glycolysis, ATP utilisation becomes coupled to the step.

28. The living differentiated plant cells, that by now have lost the capacity to divide can regain the capacity of division under all conditions.

29. Proteins are oxidised to release energy.

30. The breakdown of the protons gradient due to movement through the F0 part of the ATPase enzyme releases enough energy for synthesis of ATP.

31. Only in the mitochondria does the breakdown of complex molecules to yield energy take place.

32. Xanthophylls are the major pigment responsible for trapping light.

33. Engelmann’s first absorption spectrum of photosynthesis resembles the action spectra of chlorophyll a.

34. Fumarate → malic acid, does not couple with the FADH₂ production.

35. During oxidative phosphorylation, CO₂ is the ultimate acceptor of electrons, and it gets reduced to water.

36. α-ketoglutaric acid → succinyl-CoA, coupled with the GTP production.

37. Spraying juvenile conifers with GAs does not hastens the maturity period, thus leading to late seed production.

38. In plants, meristems are the sites of growth.

39. Dedifferentiation allows cells to regain the ability to divide and differentiate into different cell types.

40. Dedifferentiation refers to the process by which specialized cells revert to a less specialized or even a stem cell-like state.

41. 3 phosphoglyceric acid – 6C compound.

42. In glycolysis, phosphoenolpyruvate is converted to pyruvic acid which is coupled with NADH production.

43. The breakdown of complex molecules to yield energy takes place in the cytoplasm.

44. In C₃ plants the cell type in which the Calvin cycle takes place is bundle sheath cells.

45. Malic acid → OAA, does not couple with the O₂ release.

46. Under high oxygen conditions, C₄ plants are moderately prone to photorespiration.

47. Cytokinins does not helps to produce adventitious shoot formation.

48. Gravity is an external factors that control plant growth.

49. Fats are respiratory substrates.

50. As electrons move through the photosystems, protons are transported from stroma to lumen of the thylakoid membrane.
