The correct Answer is:
### Step-by-Step Text Solution: 1. **Understanding Secondary Xylem**: The secondary xylem, commonly known as wood, is produced by the vascular cambium and is responsible for the conduction of water and nutrients in plants. It consists of two main regions: sapwood and heartwood. 2. **Identifying the Peripheral Region**: The peripheral region of the secondary xylem refers to the outer layer of the wood. This area is primarily composed of sapwood. 3. **Characteristics of Sapwood**: - **Light in Color**: The sapwood is generally lighter in color compared to heartwood. - **Functional**: The sapwood is functional, meaning it is actively involved in the conduction of water and nutrients. It contains living cells that facilitate these processes. 4. **Contrasting with Heartwood**: The heartwood, which is located towards the center of the tree, is darker, non-functional, and primarily serves a structural role. It is composed of dead cells and is harder and more durable. 5. **Conclusion**: Therefore, the correct description of the peripheral region of the secondary xylem is that it is "light and functional," as it consists of sapwood that plays an active role in the plant's physiology. ### Final Answer: The peripheral region of the secondary xylem is **light and functional**. ---
