Megasporangiun Undergo Meiosois To Form - First, the number of cells within the megasporangium that undergo meiosis (each termed a megasporocyte or megaspore mother. Among a pool of the somatic cells in the ovule primordium, only one hypodermal cell undergoes a transition of cell fate to become the mmc. Angiosperms exhibit three patterns of megasporogenesis: Megasporogenesis refers to the development of megaspores from the megasporocyte, the cell that undergoes meiosis.
