The correct Answer is:
To solve the question regarding the shape of the vegetative shoot apex or stem apical meristem, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Structure**: The vegetative shoot apex, also known as the stem apical meristem, is the growing tip of the plant where new growth occurs. 2. **Identify the Regions**: The shoot apex consists of two main regions: - **Summit**: This is the topmost part of the apex where cell division occurs slowly. - **Flank**: This region is located just below the summit and has a faster rate of cell division. 3. **Analyze the Shape**: Due to the arrangement and growth patterns of these regions, the overall shape of the vegetative shoot apex is influenced by the slow growth at the summit and the faster growth at the flanks. 4. **Determine the Shape**: The combination of these two regions results in a shape that is typically conical or dome-shaped, rather than broad, broad and flat, or narrow. 5. **Select the Correct Option**: Based on the analysis, the correct answer to the question is: - (a) Conical ### Final Answer: The vegetative shoot apex or stem apical meristem is (a) Conical. ---
