Integrative Biology 102: Lecture Outline
Plant Structures for Capturing Energy & Water

Lecture Objectives:

By the end of the lecture you should be able to:

1. diagram a transverse section of a leaf and root and label cell types.
2. explain the function of each cell type for roots and leaves.
   
3. list the major functions of roots.
4. list the major and other functions of leaves.
5. explain how leaf and root cell structure reflect their functioning in the plant body.
   

Reading: Pages 37 (starting at Roots) to page 44 (ending at Vegetables: Edible Plant Organs) in Levetin & McMahon Chapter 3
