A weed that forms a rosette of leaves in year one and flowers in year two is classified as which life cycle?

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

Answer: (A)

A biennial weed is defined by a two-year life cycle: it spends year one vegetative, often forming a rosette of leaves, overwinters, and then flowers in year two to produce seeds. This pattern matches the described plant, which forms a rosette in the first year and blooms in the second. Annuals complete everything in one growing season, perennials live for multiple years and may flower in several seasons, and ephemerals are very short-lived plants that finish quickly. So the two-year progression with a rosette first and flowering second is why biennial is the best fit.
