1. In respiration, ATP synthesis is not linked to development of a proton gradient across a membrane.

2. Citric acid → isocitric acid, does not couple with the O₂ release.

3. When proton carrier molecule passes on its electron to the electron carrier on the inner side of the membrane, the proton is released into the inner side or the lumen side of the membrane.

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

5. α-ketoglutaric acid → succinyl-CoA, coupled with the NADH production.

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

7. All living differentiated plant cells, that by now have lost the capacity to divide cannot regain the capacity of division under certain conditions.

8. Fumarate → malate, does not couple with the GTP production.

9. Malic acid → OAA, coupled with the GTP production.

10. Growth is one of the most conspicuous events in any living organism.

11. Green plants make their own food by photosynthesis.

12. Proteins can be used as respiratory substances.

13. Since the discovery of zeatin, several naturally occurring cytokinins, and some synthetic compounds with cell division promoting activity, have been identified.

14. Succinyl-CoA → succinate, does not couple with the CO₂ release.

15. The breakdown of complex molecules to yield energy takes place in the mitochondria but not in the cytoplasm.

16. Scientists also tried to know whether all plants have PGA as the first product of CO₂ fixation, or whether any other product was formed in other plants.

17. Pyruvic acid is transported into the cytoplasm where it is converted into acetyl CoA with the release of CO₂.

18. Blue region of the absorption spectrum shows minimum rate of photosynthesis.

19. Auxin is an example of extrinsic factor that affects the development of a plant.

20. 2H2A+CO₂ → 2A+CH₂O+H₂O is a reaction of photosynthesis.

21. All living differentiated plant cells, that by now have lost the capacity to divide can regain the capacity of division under certain conditions.

22. Root and shoot apical meristems always along with lateral meristem, contribute to the elongation growth of plant axes.

23. Fructose 6 phosphate – 3C compound.

24. Cytokinins helps to produce new leaves, chloroplasts in leaves, lateral shoot growth and adventitious shoot formation.

25. Growth is indeterminate in higher plants.

26. Carbohydrate is a respiratory substrate.

27. The first stable product identified during fixation in plants was 3-phosphoglyceric acid or in short PGA.

28. When a cell loses the capacity to divide, it leads to differentiation.

29. Natural cytokinins can be synthesised in developing shoot buds.

30. Growth conspicuously involves decreased protoplasmic material.

31. 2 phosphoglyceric acid – 6C compound.

32. Water is an example of intrinsic factor that affects the development of a plant.

33. In glycolysis, Glucose 6 phosphate is converted to fructose 6 phosphate which is coupled with ATP production.

34. Tracheary elements are specialized cells found in the xylem tissue of liverworts.

35. Succinate → Fumarate, does not couple with the CO₂ release.

36. The cytoplasm alone is the site where the breakdown of complex molecules for energy release takes place.

37. Experiments conducted over a wide range of plants led to the discovery of another group of plants, where the first stable product of CO₂ fixation was 4 carbon inorganic acid.

38. Engelmann’s first absorption spectrum of photosynthesis does not resemble the action spectra of chlorophyll a.

39. Chlorophyll a is the major pigment responsible for trapping light.

40. Using a prism, Jan Ingenhousz split light into its spectral components and then illuminated a green alga, Cladophora, placed in a suspension of aerobic bacteria.

41. Gibberellic acid (GA3) was one of the first gibberellins to be discovered and remains the most intensively studied form.

42. In glycolysis, phosphoenolpyruvate is converted to pyruvic acid which is do not coupled with ATP production.

43. Sachs found that the non-green parts of plants is where sucrose is made, and that the sucrose is usually stored as cellulose.

44. Dormancy of a plant is influenced by both intrinsic and extrinsic factors.

45. Photosynthesis has two stages: the light reaction and the carbon fixing reactions.

46. Fumarate → malonate, coupled with the NADH production.

47. Dormancy of a plant is influenced by only intrinsic factors.

48. Following cell division in root and shoot apical meristem cells, the growth could be only geometrical.

49. In eukaryotic organisms, aerobic respiration occurs in the absence of oxygen.

50. There are more than one hundred gibberellins reported from widely different organisms such as fungi and higher plants.
