Seedless and Seed bearing Vascular Plants Seedless and Seed bearing
Vascular Plants Conducting tissue Xylem and phloem Transport water and dissolved substances Larger and more variety of habitats compared to nonvascular plants
Seedless Vascular Plants Fern allies Phylum Psilophyta Phylum Lycophyta Phylum Sphenophyta Phylum Pteridophyta
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
Phylum Lycophyta Club mosses (resemble minature pine trees) Produce strobilus or cone Cluster of sporangia – bearing modified leaves
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
Phylum Pteridophyta Diverse group of ferns Most have an underground stem call a rhizome
