• Evolution is emphasized at the molecular, cellular, organismal (as in the evolution of developmental patterns in plants), and plant community levels.
• The ecological significance of prokaryotes, fungi, bryophytes (Sphagnum, in particular), and the root systems of plants to the global carbon cycle and global warming is emphasized.

• Fully illustrated for visual learners
• Chapter Outline and Checkpoint Questions guide the students' reading
• EndofChapter Summaries as well as Summary Tables help students review the material
