Question
How many megaspore mother cells are required to produce 100 Polygonum type embryo sacs?
Easy
Solution
A seven celled, eight nucleate embryo sac is also called Polygonum type of embryo sac. For the formation an embryo sac one megaspore mother cell undergoes meiosis and produce 4 haploid megaspores. Out of these three megaspores degenerate and only one megaspore remains functional which is involved in the formation of the embryo sac.
Therefore, for the production of 100 Polygonum type embryo sac there is the requirement of 100 megaspore mother cell.
