3.6 Plants & Fungi Flashcards

6426146098	root	an organ in vascular plants that anchors the plant and enables it to absorb water and minerals from the soil	0
6426146100	vascular tissue	plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body	1
6426146109	xylem	the woody part of plants: the supporting and water-conducting tissue, consisting primarily of tracheids and vessels	2
6426146110	phloem	vascular plant tissue consisting of living cells arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant	3
6426146111	lignin	a complex polymer that provides rigidity to plant cells	4
6426146117	cuticle	a waxy covering on the surface of stems and leaves that acts as an adaptation that prevents desiccation in terrestrial plants.	5
6426146118	stomata	the small openings on the undersides of most leaves through which oxygen and carbon dioxide can move	6
6426146119	guard cells	The two cells that flank the stomatal pore and regulate the opening and closing of the pore.	7
6426146127	root hairs	tiny hair-like extensions that increase the surface area of the root allowing it to absorbs more water and nurtients	8
6426146137	transpiration	the passage of water vapor through stomata on leaves	9
6426146141	flower	reproductive organ of angiosperm plants especially one having showy or colorful parts	10
6426146142	stamen	the pollen-producing reproductive organ of a flower, consisting of an anther and a filament	11
6426146143	filament	in an angiosperm the stalk portion of the stamen, the pollen producing reproductive organ of a flower	12
6426146144	anther	in an angiosperm, the terminal pollen sac of a stamen, where pollen grains containing sperm-producing male gametophytes form	13
6426146145	carpel	the ovule producing organ of a flower, consisting of the stigma, style and ovary	14
6426146146	stigma	the sticky part of a flower's carpel, which traps pollen grains	15
6426146147	style	the stalk of a flower's carpel, with the ovary at the base and the stigma at the top	16
6426146148	ovary	in flowers, the portion of a carpel in which the egg-containing ovules develop	17
6426146149	ovule	a structure that develops within the ovary of a seed plant and contains the female gametophyte	18
6426146150	sepal	a modified leaf in angiosperms that helps enclose and protect a flower bud before it opens	19
6426146151	pollen grain	in seed pants a structure consisting of the male gametophyte enclosed within a pollen wall	20
6426146156	fruit	a mature ovary of a flower. the fruit protects dormant seeds and often aids in their dispersal	21
6426146162	auxins	A natural plant hormone that has a variety of effects, including cell elongation, root formation, secondary growth.	22
6426146165	ethylene	the only gaseous plant hormone. among its many effects are response to mechanical stress, programmed cell death, leaf abscission, and fruit ripening	23
6426146167	plant tropism	A plant response in which the direction of the response is related from which the stimulus comes.	24
6426146168	gravitropism	a response of a plant or animal to gravity	25
6426146169	phototropism	growth of a plant shoot toward or away from the light	26
6426146170	thigmotropism	plant growth in response to touch	27
6426146171	photoperiodism	a physiological response to photoperiod, the relative lengths of night and day. and example of photoperiodism is flowering.	28
6426146172	long-day plants	a plant that flowers only when the light period is longer than critical length	29
6426146173	short-day plants	a plant that flowers only when the light period is shorter than a critical length	30
6426332020	mycelium	the branched network of hyphae in a fungus	31
6426366176	Fungi	heterotrophic eukaryotes that feed by absorption	32
6426391171	bryophyte	seedless nonvascular plants. gametophyte dominant. e.g. mosses	33
6426398568	pteridophyte	seedless vascular plants. sporophyte dominant. e.g. ferns	34
6426407751	gymnosperms	seeded vascular plant. "naked" seeds housed in cones. e.g. pine, spruce, fir	35
6426417174	angiosperms	seeded vascular plant. produces flowers, fruits. e.g. grasses deciduous trees	36
6427518160	adhesion	The attraction between different kinds of molecules.	37
6427522005	cohesion	The binding together of like molecules (i.e. water), often by hydrogen bonds.	38
9362721756	phytochrome	plant pigment responsible for photoperiodism	39
9362732357	dermal tissue	The plant's outer protective covering	40
9362767075	ground tissue	tissue found between the vascular and dermal tissue	41
