Plant Anatomy and Physiology
Campbell's does not cover plant anatomy and physiology at the depth required for USABO, so we suggest reading select chapters of Raven's plant biology. Specifically, look at chapters 2, 19, 20, and 22-30. Pay special attention to the diagrams and identifying major anatomical features/cells. For more specific information, take a look at the handouts below:
Through this University of Rhode Island class page, practice identifying dicot/monocot root and stem sections, as well as the cell types within them.
Through this University of Central Oklahoma class page, study especially lecture notes on roots and stems.
