Which statement is NOT a listed reason why perennial weeds can compete from the start of the growing season?

• A. Are already established in the habitat
• B. Have storage organs
• C. Vegetative reproduction
• D. They rely solely on seeds for reproduction

Answer: (D)

Perennial weeds can hit the ground running at the start of the season because they stay in the area year after year and have stored energy to draw on. Their underground storage organs—like tubers, rhizomes, or thick roots—provide reserves that fuel early growth, so shoots emerge quickly even before photosynthesis fully ramps up. They also spread vegetatively, producing new plants from root fragments or stolons, which helps establish dense stands without needing to rely on seed production. Relying solely on seeds doesn’t fit their typical advantage; while seeds may be part of their life cycle, the ability to regrow from stored reserves and reproduce vegetatively is what gives them the early-season edge.
