8639258108	Bryophyte	Member of an early-evolving plant lineage with a gametophyte-dominant life cycle; a moss, liverwort, or hornwort.	1
8639258109	Carpel	Of flowering plants, a reproductive structure that produces female gametophytes; consists of a stigma, a style, and an ovary.	2
8639258110	Coal	Fossil fuel formed over millions of years by compaction and heating of plant remains.	3
8639258111	Coevolution	The joint evolution of two closely interacting species; each species is a selective agent for traits of the other.	4
8639258112	Conifers	Gymnosperm with non motile sperm and woody cones; for example, pines.	5
8639258113	Cuticle	Secreted covering at a body surface.	6
8639258114	Cycads	tropical or subtropical gymnosperms with flagellated sperm, palmlike leaves, and fleshy seeds	7
8639258115	Double Fertilization	in flowering plants only, one sperm fertilizes an egg to produce a zygote and another fertilizes a diploid cell to create a triploid cell that will develop into endosperm	8
8639258116	Embryophyte	land plants; clade of multicelled, photosynthetic species that protect and nourish the embryo on the parental body	9
8639258117	Endosperm	triploid (3n) nutritive tissue in an angiosperm seed	10
8639258118	Epiphytes	plants that grow on another plant but do not harm it	11
8639258119	Eudicots	most diverse lineage of angiosperms; members have two seed leaves, branching leaf veins	12
8639258120	Flower	specialized reproductive shoot of a flowering plant	13
8639258121	Fruit	Mature ovary of a flowering plant; encloses a seed or seeds.	14
8639258122	Gametangia	Gamete-producing organ of a plant.	15
8639258123	Gametophyte	A haploid, multicelled body that produces gametes in the life cycle of land plants and some algae.	16
8639258124	Ginkgo	Deciduous gymnosperm with flagellated sperm, fan-shaped leaves, and fleshy leaves.	17
8639258125	Gnetophyte	Shrubby or vine like gymnosperm, with nonmotile sperm; for example, Ephedra.	18
8639258126	Gymnosperm	Seed plant that does not make flowers or fruits; for example, a conifer.	19
8639258127	Lignin	Material that stiffens cell walls of vascular plants.	20
8639258128	Megaspores	the larger of the two kinds of spores produced by some ferns.	21
8639258129	Microspores	The smaller spore produced by sporophytes and develop into male gametophyte	22
8639258130	Monocots	an angiospermous plant of the class Monocotyledones, characterized by producing seeds with one cotyledon and an endogenous manner of growth.	23
8639258131	Ovary	the enlarged lower part of the pistil in angiospermous plants, enclosing the ovules or young seeds.	24
8639258132	Ovules	the plant part that contains the embryo sac and hence the female germ cell, which after fertilization develops into a seed.	25
8639258133	peat bogs	a swamp in which peat has accumulated	26
8639258134	Phloem	the part of a vascular bundle consisting of sieve tubes, companion cells, parenchyma, and fibers and forming the food-conducting tissue of a plant.	27
8639258135	Plants	multicelled, typically photosynthetic eukaryotes adapted to life on land.	28
8639258136	pollen grain	male gametophyte of a seed plant	29
8639258137	pollen sacs	of seed plants, sporangium where microspores form and develop into pollen grains	30
8639258138	Pollination	arrival of a pollen grain on the egg bearing part of a seed plant	31
8639258139	Pollinator	animal that moves pollen, therefore facilitating pollination	32
8639258140	Rhizoids	threadlike structures that anchor a bryophyte	33
8639258141	Rhizome	stem that grows horizontally along or under the ground	34
8639258142	Secondary Metabolite	Are organic compounds that are not directly involved in the normal growth, development, or reproduction of an organism.	35
8639258143	Seed	the fertilized, mature ovule of a flowering plant, containing an embryo or rudimentary plant.	36
8639258144	Seed Plant	The spermatophytes, also known as phanerogams or phanerogamae, comprise those plants that produce seeds, hence the alternative name seed plants. They are a subset of the embryophytes or land plants.	37
8639258145	Sporangium	a receptacle in which asexual spores are formed.	38
8639258146	Sporophyte	the asexual and usually diploid phase, producing spores from which the gametophyte arises.	39
8639258147	Stamen	The male part of the flower, containing a pollen-containing anther and a filament	40
8639258148	Stomata	Closable gaps defined by guard cells on plant surfaces, and when opened, they allow water vapor and gases to diffuse across the epidermis.	41
8639258149	Strobilus, strobili	A cluster of spore producing structures in nonflowering plants	42
8639258150	Vascular plant	A plant having specialized tissues that transport water and sugar within the plant body	43
8639258151	vascular tissue		44
8639258152	Xylem	the vascular tissue in plants that conducts water and dissolved nutrients upward from the root and also helps to form the woody element in the stem.	45
