Q21. Mendel’s principle of inheritance is based on:
  • (A) Asexual reproduction
  • (B) Vegetative reproduction
  • (C) All of the above
  • (D) Sexual reproduction
Show Answer ▼
Correct answer is Sexual reproduction. Mendel’s principles are based on sexual reproduction because traits are inherited through gametes.
Q22. Genome mapping is related to:
  • (A) Mapping of brain
  • (B) Mapping of genes
  • (C) Blood grouping
  • (D) Mapping of nerve centres
Show Answer ▼
Correct answer is Mapping of genes. Genome mapping identifies the location of genes on chromosomes.
Q23. Who is called the father of modern genetics?
  • (A) Gregor Johann Mendel
  • (B) Charles Darwin
  • (C) Hugo De Vries
  • (D) Thomas Hunt Morgan
Show Answer ▼
Correct answer is Gregor Johann Mendel. Mendel is called the father of modern genetics because of his experiments on inheritance in pea plants.
Q24. Mendel conducted his classic inheritance experiments on:
  • (A) Drosophila
  • (B) Garden pea
  • (C) Snapdragons
  • (D) Wheat
Show Answer ▼
Correct answer is Garden pea. Mendel used pea plants because they have clear, contrasting traits and are easy to cultivate.
Q25. The sugar present in DNA is:
  • (A) Glucose
  • (B) Ribose
  • (C) Fructose
  • (D) Deoxyribose
Show Answer ▼
Correct answer is Deoxyribose. DNA contains deoxyribose sugar in its backbone, differentiating it from RNA which has ribose.
Q26. The structure that differentiates plant cells from animal cells is:
  • (A) Nucleus
  • (B) Mitochondria
  • (C) Protoplasm
  • (D) Cell wall
Show Answer ▼
Correct answer is Cell wall. Plant cells have a rigid cell wall made of cellulose, which animal cells lack.
Q27. Which organelle is called the ‘Power House’ of the cell?
  • (A) Centrosome
  • (B) Mitochondria
  • (C) Ribosome
  • (D) Chloroplast
Show Answer ▼
Correct answer is Mitochondria. Mitochondria generate ATP, providing energy to the cell, hence called the ‘Power House’.
Q28. Corpus luteum is found in:
  • (A) Brain
  • (B) Ovary
  • (C) Pancreas
  • (D) Spleen
Show Answer ▼
Correct answer is Ovary. Corpus luteum forms in the ovary after ovulation and secretes progesterone to maintain pregnancy.
Q29. Which of the following is not found in animal cells?
  • (A) Nucleus
  • (B) Cytoplasm
  • (C) Plasma membrane
  • (D) Cell wall of cellulose
Show Answer ▼
Correct answer is Cell wall of cellulose. Animal cells lack a cellulose cell wall, which is present in plant cells.
Q30. Which process generates the maximum number of ATP molecules?
  • (A) Kreb’s cycle
  • (B) Electron transport
  • (C) Decomposition of glucose
  • (D) Glycolysis
Show Answer ▼
Correct answer is Electron transport. The electron transport chain generates the most ATP during cellular respiration, approximately 34 ATP molecules per glucose molecule.
