What plant type lives for more than two years?

The correct answer is that a perennial plant lives for more than two years. Perennials are characterized by their ability to survive through multiple growing seasons, coming back year after year. They typically have a life cycle that allows them to persist beyond just one growing season. This resilience may manifest as the plant dying back in winter and re-emerging in spring, or it may remain green and active year-round in milder climates.

In contrast, annual plants complete their entire life cycle—from germination to the production of seeds—within a single growing season. After they produce seeds, they die. Biennials have a life cycle that spans two years, typically growing foliage in the first year and flowering and setting seeds in the second before dying. A root crop refers more to a type of plant that is cultivated primarily for its edible underground parts, like carrots or beets, and does not specifically define the lifespan of the plant.

Thus, the defining characteristic of perennials is their longevity, making them the correct answer in this context.
