This weed germinates in the spring develops a root system and a low-growing cluster of leaves called a rosette?

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

Answer: (D)

A biennial weed follows a two-year life cycle. In the first year, it germinates in spring and develops a root system with a low, ground-hugging rosette of leaves. In the second year, it supplies more growth, sends up a flowering stalk, and then completes its life cycle, typically dying after flowering. That two-year pattern, starting with a rosette, is the hallmark of biennials.

An annual finishes its life cycle in one growing season, so you wouldn’t expect a second-year rosette leading to flowering. A perennial lives for many years and doesn’t follow a strict two-year sequence. Monocarpic means it flowers once and then dies, which can describe biennials, but the key identifying feature here is the two-year life cycle with a rosette in the first year, pointing to biennial.
