Across
- 6. a polyphyletic group of non-motile organisms traditionally described as "thalloid plants", "relatively simple plants" or "lower plants".
- 7. a division of non-vascular land plants commonly referred to as hepatics or liverworts.
- 9. plants that bear flowers and fruits, and form the clade Angiospermae, commonly called angiosperms.
- 12. mall, non-vascular flowerless plants in the taxonomic division Bryophyta sensu stricto.
- 13. a major group of eukaryotes, comprising the photoautotrophic red algae, green algae, land plants, and the minor group glaucophytes.
Down
- 1. a division of plants, grouped within the gymnosperms, that consists of some 70 species across the three relict genera: Gnetum, Welwitschia, and Ephedra.
- 2. one of the oldest groups of eukaryotic algae.
- 3. also called tracheophytes or collectively Tracheophyta, form a large group of land plants that have lignified tissues for conducting water and minerals throughout the plant.
- 4. a group of cone-bearing seed plants, a subset of gymnosperms.
- 5. a taxon of green algae informally called chlorophytes.
- 8. a genus of gymnosperms, the sole genus in the family Gnetaceae within the Gnetophyta.
- 10. a subclass of Equisetopsida in the sense used by Mark W. Chase and James L. Reveal in their 2009 article "A phylogenetic classification of the land plants to accompany APG III." This subclass comprises the conifers.
