Which plant group completes its life cycle in two years?

Explanation:
A plant that completes its life cycle in two years is a biennial. The two-year pattern means it spends the first year growing and storing energy (often forming a rosette or underground storage organ), then in the second year it flowers, sets seed, and dies. This distinguishes biennials from annuals, which finish everything in one year, and perennials, which live for multiple years and can flower across several seasons. Monocarpic describes plants that flower once and then die, but the timing of that single flowering can vary and isn’t defined strictly as two years. Classic examples of biennials include carrots, beets, and foxglove.
