The least number of meiotic divisions to form 120 seeds in a typical angiospermic plant is
View answer and explanation
Correct option: A
Option A () is correct because to form 120 seeds, 120 fertilizations are required. This means 120 eggs and 120 pollen grains are needed. To produce 120 eggs, 120/1 = 120 meiotic divisions are required. To produce 120 pollen grains, since one meiosis produces 4 pollen grains, 120/4 = 30 meiotic divisions are required. Therefore, the total number of meiotic divisions is 120 + 30 = 150.
