Leaves are the main sites of photosynthesis. Name a local plant that has photosynthesis in its stem. Distinguish nodes from internodes, tell where buds are located, and indicate how cross sections of monocot stems differ from those of dicot stems. Briefly describe how leaves develop and how they are arranged on stems. A root tip has a dome-shaped mass, called the root cap.
Root hairs are epidermal cell extensions that increase absorptive surface area.
Define the vascular cylinder. Explain the location and function of the endodermis. Distinguish between the taproot system and the fibrous root system in terms of structure and developmental origins. Describe the activity of the vascular cambium and the cork cambium. Girdling is a process of stripping off a band of phloem all the way around the tree.
