15. We come across meiosis during gametogenesis in plants and animals.

16. The detailed description of living form and appearance only brought out their diversity.

17. Cell wall is present in plant cell.

18. Meiosis involves pairing of non-homologous chromosomes and recombination between non-sister chromosomes of non-homologous chromosomes.

19. The detailed description of living form and appearance brought out biodiversity.

20. The sites at which crossing over occurs between sister chromatids of the non-homologous chromosomes are recombination nodules.

21. A nucleic acid containing deoxyribose is called ribonucleic acid (RNA)

22. Adenine and Guanine are unsubstituted pyrimidines while the rest are unsubstituted purines.

23. Nucleic acids (RNA and DNA) are not composed of nucleotides.

24. Mitosis thus, is the equational division in which the chromosome number of the parent is conserved in the daughter cell.

25. Biomacromolecules may or may not exhibit a hierarchy of structures, including primary, secondary, tertiary, and quaternary.

26. The interphase is the time during which the cell is preparing for division by undergoing both cell growth and DNA replication in a random manner.

27. There are only a few types of amino acids and nucleotides.

28. Pachytene is shorter than zygotene.

29. Plastids are pigment containing organelles found in plant cells only.

30. G2 phase corresponds to the interval between mitosis and termination of DNA replication.

31. Food vacuoles are formed by phagocytosis of the food particles.

32. While at Cambridge, Ramachandran met Linus Pauling and was deeply influenced by his publications on models of the α-helix and β-sheet structures that directed his attention to solving the structure of collagen.

33. S phase (Synthesis) is a subphase under interphase.

34. The interphase is called as resting phase.

35. The relative abundance of carbon and hydrogen with respect to other elements is higher in Earth’s crust than in in any living organism.

36. Lysosomes are membrane bound vesicular structures formed by the process of packaging in the smooth endoplasmic reticulum (SER).

37. The most abundant chemical in living organisms is not water.

38. Meiosis involves two sequential cycles of nuclear and cell division called meiosis I and meiosis II but only a single cycle of DNA replication.

39. The relative abundance of carbon and hydrogen with respect to other elements is higher in any living organism than in earth’s crust.

40. Chromosome synapsis is accompanied by the formation of synaptonemal complex.

41. The weight of a piece of liver or a leaf immediately after collected from organisms is known as dry weight.

42. Biomacromolecules are not exclusively polymers.Biomacromolecules are made of different building blocks.

43. Nucleic acids do not carry hereditary information and are not passed on from parental generation to progeny.

44. Succinate is an inhibitor of succinic dehydrogenase. 

45. The nucleus is enclosed by nuclear envelope, a double membrane structure with nuclear pores.

46. Fats and oils consist of glycerides, wherein fatty acids are esterified to glycerol.

47. The enzymes of lysosomes are not inactive at acidic pH, since hydrolytic enzymes specifically function there.

48. ER helps in the transport of substances, synthesis of proteins, lipoproteins and glycogen.
