Document Summary

Photoautotrophic photosynthetic sporophyte, gametophyte nourished by symbiotic fungi. Vascular tissues transport food and water, plus give support to plant. True stems & roots, lycophyll leaves (single vein of vascular tissue. Rhizomes horizontal stems, spreads organism across forest floor. Symbiosis between gametophyte & fungi allows gametophyte to remain protected underground (from drying out & damage) Asexually via rhizome spreading just under surface or across surface of soil. Sexually sporic life cycle or alternation of generations, spores are the only product of meiosis.
