Match List-I with List-II regarding pollen grains. List-I List-II A. Rice I. Viable for months B. Solanaceae II. Stored at -196^ C C. Pollen banks III. Lose viability within 30 minutes Choose the correct answer from the options given below:
Options
- AA-I, B-III, C-II
- BA-III, B-I, C-II
- CA-III, B-II, C-I
- DA-I, B-II, C-III
Correct answer
B. A-III, B-I, C-II
Step-by-step solution
According to NCERT, in some cereals such as rice and wheat, pollen grains lose viability within 30 minutes of their release (A matches III). Members of families like Rosaceae, Leguminosae, and Solanaceae maintain pollen viability for months (B matches I). Pollen grains of a large number of species can be stored for years in liquid nitrogen at -196^ C in pollen banks (C matches II). Therefore, the correct match is A-III, B-I, C-II. Answer: A-III, B-I, C-II
