Classification of plants

1. A group of bryophytes with simple leaves and stems, and rhizoids for anchoring. Example: Funaria.
5. Mosses Pteridophytes resembling mosses but with vascular tissue. Example: Lycopodium.
8. Seed-producing plants that do not form flowers or fruits, with exposed seeds typically on cones.
9. Gymnosperms with needle-like leaves and cones. Example: Pinus (pine trees).
12. Vascular plants that reproduce via spores and have true roots, stems, and leaves.
14. A diverse group of gymnosperms that share some characteristics with angiosperms. Example: Ephedra.
16. Red algae; contains chlorophyll a and phycobiliproteins, mostly marine and used in food and industry. Example: Porphyra.
17. The dominant life stage in pteridophytes, producing spores via meiosis.
19. Bryophytes with flattened thallus bodies, found in damp, shady areas. Example: Marchantia.

2. A filamentous green algae known for its spiral chloroplasts, found in freshwater habitats.
3. Pteridophytes with large, divided leaves called fronds, reproducing via spores on the underside. Example: Pteris.
4. Brown algae; contains chlorophyll c and fucoxanthin, typically found in marine environments. Example: Fucus.
5. Gymnosperms with large, compound leaves and stout trunks. Example: Cycas.
6. Non-vascular plants that reproduce via spores, typically found in moist environments.
7. The dominant, photosynthetic life stage in bryophytes, producing gametes.
10. Bryophytes with horn-like sporophytes that grow from a basal thallus. Example: Anthoceros.
11. Green algae; characterized by chlorophyll a and b, and cell walls made of cellulose. Example: Chlamydomonas.
13. Simple, photosynthetic organisms found in aquatic environments, lacking true roots, stems, and leaves.
15. Pteridophytes with jointed stems and silica deposits in their tissues. Example: Equisetum.
18. A single extant species (Ginkgo biloba) with fan-shaped leaves and unique reproductive structures.
