Question

How many meiotic divisions are required for the formation of 200 seeds of Capsella?

Answer 1

since we know that   one meiotic division results in 4 pollen grainsand 4 meiotic division results in 4 eggs            to produce 200 pollen  =  200/4 = 50 meiotic divisions are required                  to produce 200 eggs, 200 meiotic divisions are required 
           So a total of 250  [50+ 200] meiotic divisions are required to produce 200 seeds of Capsella
