• 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
