This weed germinates in the spring and forms a rosette; what life cycle is it?

• A. Annual
• B. Monocarpic
• C. Perennial
• D. Biennial

Answer: (D)

A weed that germinates in spring and forms a rosette in its first year is exhibiting a two-year life cycle. In biennials, the first year is spent growing and storing energy, often creating a rosette close to the ground. It overwinters in this rosette, and in the second year it produces a flowering stalk, sets seed, and then dies. The clue here—the rosette formed in the first year after spring germination—fits that two-year pattern best. While some plants may flower only once (monocarpic), the described growth sequence specifically points to a biennial life cycle.
