Which statement about weed lifecycles is correct?

• A. Annuals complete their life cycle in one year.
• B. Biennials require two years to complete their life cycle.
• C. Perennials complete their life cycle in one year.
• D. All weed lifecycles complete in one year.

Answer: (A)

Weed lifecycles describe how long a plant lives and completes its life cycle from germination to seed production. An annual weed finishes its life cycle in one growing season: it germinates, grows, reproduces, sets seeds, and dies all within that single year. This is the clearest and most definite way to define an annual and is why this statement is the best answer. Biennials, in contrast, typically require two growing seasons to complete their cycle—often forming a vegetative plant the first year and flowering and seeding in the second year before dying. Perennials live for more than two years and can flower across multiple seasons. The claim that all weed lifecycles finish in one year isn’t true because many weeds persist beyond a single season.
