front 1 Angiosperm | back 1 A flower plant, which forms seeds inside a protective chamber called an ovary. |
front 2 Bryophyte | back 2 An informal name for a moss, liverwort, or hornwort; a nonvascular plant that lives on land but lack some of the terrestrial adaptations of vascular plants. |
front 3 Cuticle | back 3 A waxy covering on the surface of stems and leaves that prevents desiccation in terrestrial plants. |
front 4 Foot | back 4 The portion of bryophyte sporophyte that gathers sugars, amino acids, water, and minerals form the parent gametophyte via transfer cells. |
front 5 Gametophore | back 5 The mature gamete-producing structure of a moss gametophyte. |
front 6 Grade | back 6 A group of organisms that share the same level of organizational complexity or share a key adaption. |
front 7 Gynmosperm | back 7 A vascular plant that bears naked seeds-seeds not enclosed in protective chambers. |
front 8 Heterosporous | back 8 Referring to a plant species that has 2 kinds of spores: microspores, which develop into gametophytes, and megaspores, which develop into female gametophytes. |
front 9 Homosporous | back 9 Referring to a plant species that has a single kind of spore, which typically develops into a bisexual gametophyte. |
front 10 Hornwort | back 10 A small, herbaceous, nonvascular plant that is a member of the phylum Anthocerophyta. |
front 11 Lignin | back 11 A hard material embedded in the cellulose matrix of vascular plant cell walls that provides structural support in terrestrial species. |
front 12 Liverwort | back 12 A small, herbaceous, nonvascular plant that is a member of the phylum Hepatophyta. |
front 13 Lycophyte | back 13 An informal name for a member of the phylum Lycophyta, which includes club mosses, spike mosses, and quillworts. |
front 14 Megaspore | back 14 A spore from a heterosporous plant species that develops into a female gametophyte. |
front 15 Microspore | back 15 A spore from a heterosporous plant species that develops into a male gametophyte. |
front 16 Phloem | back 16 Vascular plant tissue consisting of living cells arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant. |
front 17 Rhizoids | back 17 Along tubular single cell or filament of cells that anchors bryophytes to the ground. Unlike roots, rhizoids are not composed of tissues, lack specialized conducting cells, and do not play a primary role in water and mineral absorption. |
front 18 Root | back 18 An organ in vascular plants that anchors the plant and enables in to absorb the plant and enables it to absorb water and minerals from the soil. |
front 19 Stoma | back 19 A microscopic pore surrounded by guard cells in the epidermis of leaves and stems that allows gas exchange between the environment and the interior of the plant. |
front 20 Tracheid | back 20 A long, tapered water-conducting cell found in the xylem of nearly all vascular plants. Functioning tracheids are no longer living. |
front 21 Vascular plant | back 21 A plant with vascular tissue. Vascular plants include all living plant species except liverworts, mosses, and hornworts. |
front 22 Vascular Tissue | back 22 Plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body. |
front 23 Xylem | back 23 Vascular plant tissue consisting mainly of tubular dead cells that conduct most of the water and minerals upward from the roots to the rest of the plant. |
