Which of the following is NOT a typical characteristic of a herbaceous plant?

Herbaceous plants are characterized by their soft, non-woody stems, which is why the presence of a wooden structure is not typical for this category of plants. Unlike woody plants, which develop hard stems that persist and support growth year after year, herbaceous plants have stems that die back at the end of the growing season. This aligns with their soft texture and seasonal growth patterns, as they often complete their life cycle within a single growing season or come back annually from their root systems.

The other characteristics mentioned, such as having a short lifespan and seasonal growth patterns, are commonly associated with herbaceous plants. Therefore, the presence of a wooden structure distinctly sets them apart from herbaceous plants, making the answer correct.
