What are biennials in plants?

• A. Plants that complete their life cycle in one year
• B. Plants that take two years to complete their life cycle
• C. Plants that live for more than two years
• D. Plants that exhibit seasonal behavior

Answer: (B)

Biennials are defined as plants that take two years to complete their life cycle. In the first year, these plants typically grow vegetatively, developing roots, stems, and leaves but not producing flowers. It's in the following year that biennials bloom, producing flowers and seeds before completing their lifecycle and dying. This growth pattern distinguishes them from annuals, which complete their cycle in a single year, and perennials, which can live for more than two years. Understanding this classification helps in gardening and cultivation, as it informs when to expect flowering and how to care for these plants across their growth phases.
