| alternation of generations | life cycle that alternates between the gametophyte phase and sporophyte phase |
| angiosperm | produces seeds within a protective fruit, also known as flowering plants |
| cuticle | a waxy protective covering on plant wurfaces that prevents water loss |
| endosperm | a tissue that provides nourishment for the developing plant |
| gametophyte | a multicellular structure that produces gametes |
| gymnosperm | produce seeds that are not enclosed in fruits |
| herbaceous | nonwoody plants that have soft, usually green stems |
| nonvascular plant | a plant that lacks vascular tissue and tree roots, stems, and leaves |
| phloem | carries organic compounds, such as carbohydrates, and some inorganic nutrients in any direction, depending on the plants need |
| seed | an embryo surrounded by a protective coat |
| seed plant | plants that produce seeds for reproduction |
| spore | haploid reproductive cell surrounded by a hard outer wall |
| sporophyte | plant that produces spores |
| vacular plant | these have vascular tissur and true roots, stems, and leaves |
| vacular tissue | a type of tissue that transports water and dissolved substances from one part of the plant to another |
| woody tissue | formed from several layers of xylem, usually concentrated in the center of the stem |

| cone | a reproductive structure composed of hard cells |
| cotyledon | seed leaves found in a plant embryo |
| deciduous | trees that lose their leaves at the end of the growing season |
| dicot | an angiosperm with two cotyledons, net venation, and flower parts in fours of fives |
