Which term describes a perennial plant that completes its life cycle in more than two years?

The term that describes a perennial plant completing its life cycle in more than two years is indeed "perennial." Perennials are plants that can live for multiple years, often returning to growth each spring after dying back in the winter. These plants typically go through a cycle of growth, flowering, and seed production multiple times over their lifespan, which can span several years to decades.

In contrast, annuals complete their life cycle in a single growing season, germinating, flowering, and dying within one year. Biennials, on the other hand, take two years to complete their life cycle, generally growing foliage in the first year and flowering in the second. Lastly, deciduous refers to plants that shed their leaves seasonally, not specifically related to their life cycle duration. Understanding these differences helps clarify the characteristics associated with various plant types.
