| epiphyte | Plant that lives anchored to an object or another plant |
| rhizoid | Type of hypha formed by a mold that penetrates a food’s surface |
| seed | Adaptive reproductive structure of some vascular plants that contains an embryo, nutrients for the embryo, and is covered by a protective coat |
| cone | Feature that contains male or female reproductive structures of cycads and other gymnosperms. |
| biennial | Plant with a 2 year life span |
| thallose | Liverwort with a fleshy, lobed body shape |
| sporangium | Sac or case in which fungal spores are produced |
| strobilus | Compact cluster of spore-bearing structures in some seedless vascular plant sporophytes |
| stomata | Openings in the outer cell layer of leaf surfaces and some stems that allow the exchange of water, carbon dioxide, oxygen, and other gases between a plant and its environment |
| vascular tissue | Specialized tissue that transports water, food, and other substances in vascular plants and can also provide structure and support |
| cotyledon | Seed structure that stores food or helps absorb food for the sporophyte of vascular seed plants |
| perennial | Plant that can live for several years |
| angiosperm | Plant whose seeds are part of fruits |
| sorus | Gamete-producing or fruiting body in certain algae and fungi |
| alternation of generations | Reproductive life cycle that alternates between a diploid sporophyte generation and a haploid gametophyte generation |
| gymnosperm | Plant whose seeds are not part of fruits |
| spore | Reproductive haploid cell with a hard outer shell that forms a new organism without the fusion of gametes and is produced in the asexual and sexual life cycles of most fungi and some other organisms |
| nonvascular plant | Type of plant that lacks vascular tissues, moves substances slowly from cell to cell by osmosis and diffusion, and grows only in a damp environment |
| vascular plant | Type of plant with vascular tissues adapted to land environments; most widely distributed type of plant on Earth |
| rhizome | Fern’s thick underground stem that functions as a food storage organ |
| annual | Plant that completes its life span in one growing season or less |
| deciduous | Tree or shrub that sheds its leaves annually |
