Which characteristic applies to plants like dandelions?

Dandelions, and similar plants, are classified as perennial weeds, and one of their defining characteristics is the presence of a tap root, which serves as a storage organ for nutrients and water. Additionally, they produce crown buds that allow them to survive adverse conditions and regrow each season. The tap root enables dandelions to anchor deeply into the soil, making them difficult to eradicate once established.

In contrast, the other options describe characteristics not typical of dandelions. For instance, many plants reproduce by seeds, including dandelions, which produce abundant seeds for further reproduction. The description of being bulbous applies to different types of plants, such as onions or garlic, not dandelions. Finally, the lifespan of dandelions far exceeds a year; they are perennials, living for several years and returning each growing season. This understanding emphasizes the specific biology and adaptation strategies of dandelions in terms of survival and reproduction.
