126290305	Sporopollenin	Prevents exposed zygotes from dying out
126290306	Apical meristmes	Localized regions of cell division at the tips of shoots and roots
126290307	Alternation of Generations	LIfe cycles of all land plants alternate between two different multicellular bodies with each form producing the other.
126290308	Gametophyte	Haploid
126290309	Sporophyte	Diploid
126290310	spores	reproductive cells that can develop into a new organism without fusing with another cell
126290311	sporangia	a multicellular organ that produce plant spores.
126290312	sporocytes	diploid cells also know as spore mother cells, create haploid spores
126290313	gametangia	multicellular organs that produce gametes
126290314	Archegonia	Female gametangia
126290315	Antheridia	male gametangia
126290316	Placental transfer cells	enhance the transfer of nutrients from parent to embryo through elaborate ingrowths of the wall surface
126290317	embryophytes	multicellular dependent embryo of land plants
126290318	Gymnosperms	naked seed plants because their seeds are not enclosed in chambers
126290319	Angiosperms	a flowering plant that forms seeds inside a protective chamber called an ovary
126290320	Protonema	Germinating moss spores produce a mass of green branched one cell thick filaments
126290321	Gametophore	a gamete producing structure formed from moss
126290322	Rhizoids	anchors gametophytes
126290323	Seta	Stalk, conducts materials to the sporangium also called a capsule
126290325	Peristome	upper part of the capsule freature a ring of toothlike structures. Specialized for gradual spore, discharge.
126290326	Stomata	specialized pores which are found in all vascular plants
126290327	Sporophyll	modified leaves that bear sporangia
126290328	sori	clusters of sporangia
126290329	strobili	groups of sporophylls form cones
126290330	homosporous	having one type of sporophyll producing one type of spore
126290331	heterosporous	two types of sporophyllis and produces two kinds of spores
126290332	megaspores	develops into female gametophytes
126290333	microspores	develops into male gametophytes
126290334	Xylem	vascular tissue that conducts water and minerals
126290335	Phloem	vascular tissue that distributes sugars, amino acids, and other organic products
126290336	lignin	polymer that strengthens cell walls
126290337	Microphyll	small, usually spine shaped leaves supported by a single strand of vascular tissue - unique to lycophytes
126290338	megaphyll	leaves with a highly branched vascular system
