New terms and changes arising from last week's discussion
During a discussion at the POC meeting on 10-18-11, we realized that it would be best to have seed be a subtype of plant structure.
Old def.: A propagating organ formed in the reproductive cycle of gymnosperms and angiosperms, derived from the ovule and enclosing an embryo. [source: APWeb:Glossary, GR:Pankaj_Jaiswal] comment: The seed is representative of a next generation of sporophyte.
New proposed def.: A plant structure that develops from an ovule and contains an embryo enclosed in a seed coat. Comment: A seed is a reproductive unit of seed plants (gymnosperms and angiosperms).
develops_from ovule, has_part embryo
Also removed seed_part of fruit relation, added to subsets for gymnosperms and angiosperms.
plant spore stage (PO:0025375)
proposed definition: A gametophyte development stage that occurs during the interval between meiosis and the germination (first cell division) of a spore.
comment: Includes the stage when a megaspore is present before it develops into a megagametophyte or embryo sac and the stage when a microspore is present before it develops into a microgametophyte or pollen.
