Detailed explanation-2: -Cells of the embryo sac divide by mitosis to give egg apparatus and accessory cells.
Detailed explanation-3: -Embryo sac develops from megaspore mother cell through. A. 1 meiosis and 2 mitosis.
Detailed explanation-4: -Solution: Three mitotic generations required to form a mature embryo sac in most of flowering plants.
