| Charophyte | common name for green plants in the order Charophyceae |
| Antheridium | In plants, the male gametangium, a moist chamber gametes develop |
| Archegonium | In plants, female gametagium, a moist chamber gametes develop |
| Sporangium | A capsule in fungi and plants in which meiosis occurs and haploid spores develop |
| Mosses | Small, herbaceous nonvascular plants that are a member of the phylum Bryophyta |
| Liverworts | Small, herbaceous nonvascular plants that are a member of the phylum Hepatophyta |
| Hornworts | Small, herbaceous nonvascular plants that are a member of the phylum Anthocerophyta |
| Xylem | Vascular plant tissue consisting mainly of tuular dead cells that conduct most of th water and minerals upward from the roots to the rest of the plant |
| Phloem | Vascular plant tissue consiting of living cells arranged into elongated tubes that transport sugar an other orgac nutrients throughout the plant |
| Homosporous | A term refering to a plant species that has a single kid of spore, which typically develops into a bisxual gametophyte |
| heterosporous | term referring to a plant species that has 2 kinds of spores: microspores that develop into male gametophytes and megaspores that develop into female gametophytes |
| megaspores | spore from a heterosporous plant species that develops into female gametophyte |
| microspores | spore from a heterosporous plant species that develops into a male gametophyte |
| lycophytes | informal name for any member of the phylum Lycophyta, which includes club mosses, spike mosses, and quillworts |
| epiphytes | plant that nourishes itself but grows on the surface of another plant for support, usually on the branches or trunks of tropical trees |
| sporophylls | leaf specialized for reproduction |
| horsetails | the only living genus in the Equisetaceae, a family of vascular plants that reproduce by spores rather than seeds |
| ferns | any of numerous flowerless and seedless vascular plants having true roots from a rhizome and fronds that uncurl upward; reproduce by spores |
| stomata | microscopic pores surrounded by guard cells in the epidermis of leaves and stems that allows gas exchange |
| cuticle | waxy covering on the surface of stems and leaves that acts as an adaptation to prevent desiccation in terrestrial plants |
| lignin | hard material embedded in the cellulose matrix of vascular plant cell walls that functions as an important adaptation for support in terrestrial species |
| sporopollenin | a secondary product, a polymer synthesized by a side branch of a major metabolic pathway of plants that is resistant to almost all kinds of environmental damage; especially important in the evolutionary move of plants onto land |
| gametangia | reproductive organs of bryophytes, consisting of the male antheridium and female archegonium; a multi-chambered jacket of sterile cells in which gametes are formed |
| gametophyte | multicellular haploid form in organisms undergoing alternation of generations, which mitotically produces haploid gametes that unite and grow into the sporophyte generation |
| sporophyte | multicellular diploid form in organisms undergoing alternation of generations that results from a union of gametes and that meiotically produces haploid spores that grow into the gametophyte generation |
| vascular tissue | plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant's body |
| gymnosperm | vascular plant that bears naked seeds not enclosed in any specialized chambers |
| angiosperm | flowering plant which forms seeds inside a protective chamber called an ovary |
