| cuticle | the waxy, waterproof layer that covers most plants |
| vascular tissue | the system of tubelike structures in plants that transport nutrients throughout the body |
| nonvascular plant | a low-growing plant that lacks true vascular tissue for transporting materials |
| rhizoid | a thin, rootlike structure that anchors a moss and absorbs water and nutrients for it |
| vascular plant | a plant that has true vascular tissue for transporting materials |
| phloem | the vascular tissue that food moves through |
| xylem | the vascular tissue that water and minerals move through |

| pollen | tiny structure produced by the seed plant that contain the cell that later becomes a sperm cell |
| seed | the plant structure that contains a young plant and a food supply inside a protective covering |
| gymnosperm | a plant that produces seeds directly on the scales of cones-not enclosed by a protective fruit |
| angiosperm | a flowering plant that produces seeds enclosed in a protective fruit |
| cotyledon | a leaf produced by an embryo of a seed plant; sometimes stores food |

| stamen | the male reproductive part of a flower |
| pistil | the female reproductive part of a flower |
| ovary | a flower structure that encloses and protects ovules and seeds as they develop |
| sporophyte | spore-producing structure |
| gametophyte | produces egg-cells and sperm-cells |
| annual | flowering plants that complete a life cycle within one growing season |
| biennial | angiosperms that complete their life cycle in two years |
| perennial | flowering plants that live for more than two years |
