- 6. plants, also known as Tracheophyta, form a large group of plants that are defined as land plants with lignified tissues for conducting water and minerals throughout the plant.
- 7. are a polyphyletic group of non-motile organisms traditionally described as "thalloid plants", "relatively simple plants" or "lower plants".
- 8. is 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."
- 10. Is a taxon of green algae informally called chlorophytes.
- 12. are a major group of eukaryotes, comprising the photoautotrophic red algae, green algae, land plants, and the minor group glaucophytes.
- 15. is a clade within the Phragmoplastophyta, a larger clade that also includes several groups of green algae including the Charophyceae and Coleochaetales.
Down
- 1. are small, non-vascular flowerless plants in the taxonomic division Bryophyta sensu stricto.
- 2. small division of the plant kingdom consisting of the plants commonly called horsetails and scouring rushes.
- 3. is a clade of plants.
- 4. are a group of cone-bearing seed plants, a subset of gymnosperms.
- 5. are one of the oldest groups of eukaryotic algae.
- 9. is a division of plants, grouped within the gymnosperms, that consists of some 70 species across the three relict genera: Gnetum, Welwitschia, and Ephedra. charophytes is a group of freshwater green algae, sometimes treated as a division, but also as a superdivision, or an unranked clade.
- 11. is a genus of gymnosperms, the sole genus in the family Gnetaceae and order Gnetales.
- 13. are a division of non-vascular land plants commonly referred to as hepatics or liverworts.
- 14. is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers.
