The best-known examples are trees and shrubs (bushes). Monocot stems, such as corn, palms and bamboos, do not have a vascular cambium and do not exhibit secondary growth by the production of concentric annual rings. The vascular system found in dicots is somewhat more complex than that found in monocots. The main difference between woody and herbaceous plants is that the woody plants have a strong stem, which is not easily bendable whereas the herbaceous plants have a flexible stem.Furthermore, woody plants are perennial plants while herbaceous plants are annuals, biennials or perennials..

Primary growth produces growth in length and development of lateral appendages. 3. WOODY DICOTS. Plant Tissues Cork. Roots, Stems and Leaves Diagrams . Secondary growth is the formation of secondary tissues from lateral meristems. It is responsible for the making and separation of both xylem and phloem. Hence, the roots crop up from the stemâs nodes. Dicot stems are normally woody. Meristematic cellasr e those that retain the ability to divide, whereas permanent cells are those that have lost this ability. Now itâs your turn! Populus is presented as a model system for the study of wood formation (xylogenesis).
