1. Seedless and Seed bearing
Vascular Plants
Seedless and Seed bearing

2. Vascular Plants Conducting tissue
Xylem and phloem
Transport water and dissolved substances
Larger and more variety of habitats compared to nonvascular plants

3. Seedless Vascular Plants
Fern allies
Phylum Psilophyta
Phylum Lycophyta
Phylum Sphenophyta
Phylum Pteridophyta

4. Phylum Psilophyta Whisk ferns Not ferns, no roots or leaves
Produce spores on ends of short branches
Some are epiphytes
grow on other plants
not parasitic

5. Phylum Lycophyta Club mosses (resemble minature pine trees)
Produce strobilus or cone
Cluster of sporangia – bearing modified leaves

6. Phylum Sphenophyta Horsetails (Equisetum)
Jointed hollow photosynthetic stem and jointed leaves
Contains silica
Grow from rhizome
Form “cones” on tips made of spores
Scouring rushes

7. Phylum Pteridophyta Diverse group of ferns
Most have an underground stem call a rhizome
