• Does not have specialized tissue to move water & nutrients
• Small plants, depend on diffusion

moss
• Don’t have true stems, roots, or leaves–Do have structures that carry out activities
• Mosses–“mat” of tiny green plants–Rhizoid
• root-like structure that holds nonvascular plants in place
• Helps plant get water and nutrients
• Liverworts & Hornworts–Similar to life cycle of mosses–Liverworts
• Gametophytes are leafy & moss-like OR broad and flattened
–Hornworts• Gametophytes are broad and flattened
• First plants to live in new environment
• Decompose to form thin soil layer for other plants
• Provide soil stability (reduce erosion)
• Food chain
• Material for nesting
• Dried and burned
• Potting soils
• Similarities in certain species suggest a common ancestor (cell wall, chlorophyll)
Modern green algae Fern
• Has tissue to deliver water & nutrients around plant
• Similar to circulatory system in humans
• Plants can be any size
Fern
Horsetail
Club Moss
• Ferns–Rhizome-underground
stem from which
new leaves and
roots grow
