What describes the physical appearance of Poison Ivy?

The physical appearance of Poison Ivy is best described as a woody shrub or vine with hairy looking aerial roots. This description is accurate because Poison Ivy typically has a growth form that can vary from a small shrub to a climbing vine, and it is often characterized by its distinct leaves that grow in clusters of three. The hairy aerial roots help the plant cling to surfaces as it grows, which is a common feature seen in climbing plants.

In contrast, the other descriptions do not accurately capture the characteristics of Poison Ivy. The option describing a small flowering plant close to the ground misrepresents the plant's potential height and climbing capabilities. The choice of a large, leafless tree is irrelevant, as Poison Ivy does not grow in tree form and has leaves that are integral to its identification. Finally, referring to it as a succulent ground cover does not align with its growth habit or appearance, as Poison Ivy does not have the fleshy, water-storing attributes typical of succulents. Therefore, the description of it as a woody shrub or vine with hairy roots is the most fitting and reflects the plant's nature.
