| 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 |
