| These final stages in development usually occur on the soil after the megaspore with the enclosed female gametophyte is shed from the megasporangium. |
| In sexual reproduction a diploid somatic cell, the megaspore mother cell, undergoes meiosis to produce four reduced megaspores. |
| The search for the mysterious plant that produced this famous megaspore continues in various locations around the world, with particular attention given to a new Spermasporites site in eastern Greenland. |
| It is in the nucellus that meiosis occurs, resulting in the formation of four haploid megaspore cells. |
| Arborescent lycopsids began life as an embryo germinating from an indehiscent megaspore. |
| The presence of a megaspore at their base excluded a vegetative origin from the mother plant, but we cannot exclude apogamy. |
