Match List-I with List-II
| List-I Terms | List-II Examples |
|---|---|
| (A) Somatic hybrid | (I) Bt toxin |
| (B) Tissue culture | (II) Apical and axillary meristem |
| (C) Insecticidal protein | (III) Pomato |
| (D) Virus free plant | (IV) Explants |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
(A) Somatic hybrid — this matches (III) Pomato. The cell walls of single cells of two plants are digested, and the naked protoplasts are fused. The fused protoplast of tomato and potato grew into the pomato, a somatic hybrid.
(B) Tissue culture — this matches (IV) Explants. An explant is any part of a plant taken out and grown in a test tube, under sterile conditions and on a special nutrient medium. A whole plant can be raised from it.
(C) Insecticidal protein — this matches (I) Bt toxin. The bacterium Bacillus thuringiensis makes a protein that kills certain insects when they eat it. Its gene is put into crops such as Bt cotton.
(D) Virus free plant — this matches (II) Apical and axillary meristem. Even in a plant infected with a virus, the meristems (apical and axillary) are free of the virus. Grown in culture, they give virus-free plants.
