Biology Plants

	the plant organ that grows from a stem in which photosynthesis usually occurs
	plants that do not have vascular tissues
	plants that have vascular tissues; enables taller growth and survival on land
	plant organ that absorbs water and minerals usually from soil; contains vascular tissues; anchors lant; can be a storage organ
	a plant organ of seed plants consisting of an embryo, a food supply, and a protective coat; protects the embryo from drying out and also can aid in dispersal
	plant organ that provides support and growth; contains tissues that transport food and water and other materials; organ from which leaves grow. Can serve as a food storage organ; green stems can carry out photosynthesis
	in ferns, leaves that grow upward from the rhizome; often divided into pinnae that are attached to a central rachis
	thick, underground stem of a fern and other vascular plants; often functions as an organ for food storage
	anthophyte that lives for one year or less
	anthophyte that has a lifespan of two years
	anthophyte that lives for several years
	structure of a seed plant embryo that stores or absorbs food for the developing embryo
	plants that drop all of their leaves each fall or when water is scarce or unavailable; an adaptation for reducing water loss when water is unavailable
	class of anthophytes that have two seed leaves
	seed-containing ripened ovary of an anthophyte flower; may be fleshy or dry
	class of anthophytes that have one seed leaf
	in seed plants. structure in which the male gametophyte develops; consists of sperm cells, nutrients and a protective outer covering
	in seed plants, the sporophyte structure surrounding the developing female gametophyte; forms the seed after fertlization
	in plants, the outermost layer of flattened cells that covers and protects all parts of the plant
	regions of actively dividing cells near the tips of roots and stems; allows roots and stems to increase in length
	regions of actively dividing cells in plants
	vascular plant tissue composed of tubular cells that transport water and dissolved minerals from the roots to the rest of the plant
	vascular plant tissue made up of tubular cells joined end to end; transports sugars to all parts of the plant
	lateral meristem that produces new xylem and phloem cells in the stem and roots
	cells that control the opening and closing of the stomata; regulate the flow of water vapor from leaf tissue
	openings in leaf tissue that control gas exchange
	in plants, the stalk that joins the leaf to the stem
	protective, waxy coating on the outer surface of the epidermis of most stems and leaves; important adaptation in reducing water loss
	growth response of a plant to an external stimulus
	haploid form of an organism in alternation of generations that produces gametes
	in algae and plants, the diploid (2n) form of an organism in alternation of generations that produces spores
	female reproductive organ of a flower
	leaflike, usually green structure encircles the top of a flower stem below the petals
	male reproductive organ of a flower consisting of an anther and a filament
	pollen producing structure located at the tip of a flower's stamen
	period of inactivity in a mature seed prior to germination
	beginning of the development of an embryo into a new plant
	tissues found in vascular plants composed of tubelike, elongated cells through which water, food and other materials are transported throughout the plant; include xylem and phloem
