The megagametophyte of the gymnosperms is homologous to the megaprothallium (n) of the ferns and is sometimes called primary endosperm (n). The megagametophyte of seed plants is retained and nourished by the parent plant within the ovule. Ovule = megagametophyte + megasporangium (nucellus) + integument (seed coat). The megagametophytes of the gymnosperms produce several archegonia (n) with egg cells (n). Fertilization by the sperm from the pollen grain (microgametophyte, male gametophye, n) often leads to the development of several embryos (2n) within a single ovule. Polyembryony of gymnosperm seeds is a known phenomenon.
An alderman is a member of a municipal assembly or council in many jurisdictions founded upon English law. The term may be titular, denoting a high-ranking member of a borough or county council, a council member chosen by the elected members themselves rather than by popular vote, or a council member elected by voters.
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from the Greek words elektron, meaning amber (from which the word electricity is derived), and hodos, a way.
