seed plants

19585700	sporophyte	the spore-producing individual or phase in the life cycle of a plant having alternation of generations
19585701	seed	embryo of a living plant that is encased in a protective covering and surrounded by a food supply
19585702	integuments	layers of sporophyte tissue that envelop and protect the megasporangium in gymnosperms.
19585703	ovule	the structure composed of a megasporangium, megaspore, and their integuments.
19585704	heterosporous	A term referring to a plant species that has two kinds of spores: microspores that develop into male gametophytes and megaspores that develop into female gametophytes.
19585705	megasporangia	where megaspores are produced from meiosis of megaspore mother cells
19585706	microsporangia	where microspores are produced that give rise to male gametophytes. the microsporangium is contained within a pollen grain
19585707	sporophylls	Modified scalelike leaves of gymnosperms where ovules and seeds develop on the surface
19585708	sporangia	multicellular organs that produce spores
19585709	monocots	A clade consisting of flowering plants that have one embyonic seed leaf, or cotyledon.
19585710	dicots	Two cotyledons. Flower parts in fours or fives, vascular tissue in distinct bundles arranged in a circle, taproot system, leaves with netted veins.
19585711	vascular tissue	Specialized tissue that transport water and nutrients to plant consists of xylem and phloem
19585712	xylem	plant vascular tissue that carries water and minerals from the roots up through a plant;helps support a plant
19585713	tracheids	long, tapered xylem cells, provide mechanical support and transport water
19585714	flower	reproductive organ of angiosperm plants especially one having showy or colorful parts
19585715	flower parts	4 circles of modified leaves: sepals. petals, stamens, carpels
19585716	sepals	Outermost leaf part of flower; protects bud
19585717	petals	parts above sepals usually colored
19585718	stamens	the male reproductive structures, the sporophylls that produce microspores,consist of anther and a filament
19585719	carpels	The female reproductive organ of a flower,that make megaspores consisting of the stigma, style, and ovary.
19585720	filament	the stalk of a stamen
19585721	anther	the terminal pollen sac of a stamen where pollen grains with male gametes form
19585722	stigma	sticky part on the end of the carpel (also called pistil) that captures pollen grains
19585723	style	the narrow elongated part at the base of the carpel ( also called pistil) that leads to the ovary
19585724	fruit	a mature ovary, ovaries are only in angiosperms
19585725	pericarp	the thickened wall of a fruit, used to be the ovary.
19585726	cross pollination	transfer of pollen from flower of one plant to the sticky stigma of another plant
19585727	double fertilization	unique to angiosperms, term used to describe one sperm fusing with the egg, while the other fuses with two nuclei in the large central cell of the famale gametophyte.results in triploid nucleus 3n
19585728	cotyledons	The structures where food is stored in seeds composed of one or two seed leaves
19585729	endosperm	a triploid tissue providing food for the embryo in angiosperms
19585730	ovules	Structure that develops within ovary of seed plant and contains female gametophyte.
