Definitions need work

Existing definitions:

sporocyte (PO:0006204): A diploid (2n) cell that undergoes meiosis and produces four haploid (1n) spores.

microsporocyte (PO:0020047): A diploid (2n) cell that undergoes meiosis and produces four haploid (1n) microspores. [source: ISBN:0878934030]
synonyms: microspore mother cell, PMC, pollen mother cell

megasporocyte (PO:0000431): A diploid (2n) cell that undergoes meiosis and produces four haploid (1n) megaspores. [source: ISBN:0471245208]
synonyms: megaspore mother cell, MMC

At the POC meeting on 5/6/11, we agreed to add sporocyte develops_from archesporial cell.
Already have:
megasporocyte develops_from female archesporial cell
microsporocyte dvelops_from primary sporogenous cell, which develops_from male archesporial cell

Revised, but definitions still need further work:
megasporocyte (PO:0000431): A sporocyte (PO:0006204) that produces four haploid (1n) megaspores (PO:0020019).

microsporocyte (PO:0020047): A sporocyte (PO:0006204) that produces four haploid (1n) microspores (PO:0020048).
