The process by which the megasporocyte undergoes meiosis, giving rise to four haploid megaspores in the nucellus. A biological process whose specific outcome is the progression of an integrated living unit: an anatomical structure (which may be a subcellular structure, cell, tissue, or organ), or organism over time from an initial condition to a later condition. The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division. Progression through the phases of the meiotic cell cycle, in which canonically a cell replicates to produce four offspring with half the chromosomal content of the progenitor cell. The process by which the microsporocyte undergoes meiosis, giving rise to four haploid microspores. Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. The process whose specific outcome is the progression of the spore over time, from its formation to the mature structure. The spore gives rise to gametophytes. A biological process whose specific outcome is the progression of a cell over time from an initial condition to a later condition.
