One diploid microspore mother cells divide by meiosis and forms 4 tetrads of haploid microspores which become 4 pollen grains. Therefore, for the formation of 200 pollen grains,
; 50 meiotic division are required.

However, when one diploid megaspore mother cell divides by meiosis, and forms 4 linearly arranged haploid megaspore, out of which 3 degenerate and only 1 megaspore develops into egg.
Therefore, 1 egg is formed by 1 meiosis in the megaspore mother cell.
So, in order to form 200 egg cells, 200 meiotic divisions are required.

Therefore, total number of meiotic divisions required to produce 40 seeds in the Capsella plant is:
