Chapter 35 - 35.3 - Concept Check - Page 769: 1


Primary growth in roots and shoots produces the same three tissue layers, but there are important differences: 1) shoots have more complex primary growth with nodes, internodes, and leaves while roots consist of roots and branch roots; 2) the presence of pith (unspecialized parenchyma in the center of the organ) varies between them (present in dicot shoots and monocot roots); the root has some specialized layers (endodermis and pericycle) not found in the shoot.
