In biennials, what occurs in Year 2?

• A. Reproduces and dies
• B. Grows taller only
• C. Dies without reproducing
• D. Becomes herbaceous but non-reproductive.

Answer: (A)

Biennials complete a two-year life cycle. In the first year they focus on vegetative growth and storing energy. In the second year they switch to reproduction, producing flowers and seeds, and then the plant typically dies. So, what happens in Year 2 is flowering, seed production, and death after reproduction. This contrasts with annuals, which die after one season, and perennials, which often keep living and may or may not flower in any given year. The idea that Year 2 centers on reproduction and subsequent death is the hallmark of biennials, which is why this option is the best description. For example, a carrot or parsley plant grows leaves in year one and then bolts and seeds in year two before dying.
