| An alignment of cytoskeletal elements and Golgi-derived vesicles in the formation of a new cell wall | ||
| A durable polymer that prevents exposed zygotes from drying out | ||
| Multicellular organs in a sporophyte that produces plant spores | ||
| Also known as spore mother cells, these diploid cells under go meiosis in a sporangium and and produce haploid spores | ||
| General term for multicellular organs that produce gametes | ||
| Female gametangia; a vase-shaped organ that produces a single egg retained at the base of the organ | ||
| Male gamentangia, which produces and releases sperm to the environment | ||
| A class of land prants that contain placental transfer cells to nourish an embryo in a seed | ||
| Non-vascular plants that include liverworts, hornworts and mosses. They feature a prominent gametophytes in their lifecycle | ||
| Oldest group of seedless plants that includes club mosses, spike mosses and quillworts | ||
| Group of seedless plants that includes ferns, horsetails and whisk ferns | ||
| Green, branched one-cell-thick filaments produced by germinating moss spores. | ||
| Gamete-producing structure in mosses that buds from protonema | ||
| Root-like structure in mosses that anchors gametophytes | ||
| The stalk of a bryophyte sporophyte | ||
| The sporangium in bryophytes | ||
| Protective cap of gametophyte tissue in bryophyte capsules | ||
| Ring of toothlike structures specialized for spore discharge in most moss species | ||
| Partially decayed organic material from the wetland moss Sphagnum | ||
| A small spine-shaped leaf with a single vein, found in all lycophytes | ||
| Leaf with a highly branched vascular system and are larger | ||
| Modified leaves in vascular seedless plants that bear sporangia | ||
| Clusters of sporangia on the undersides of fern sporophylls | ||
| Groups of sporophylls that form cones in many lycophytes and most gymnosperms | ||
| Trait when one type of sporophyll produces on type of spore that develops into a bisexual gametophyte; most dominant | ||
| Produces two types of sporophylls, produces megaspores and microspores; seed plants and a few seedless vascular plants are this | ||
| The period in which the ancestors of seedless vascular plants thrived and grew to great heights; source of coal |
