Which term describes plants that produce seeds every 2 years?

1. Annual

2. Perennial

3. Biennial

4. Seasonal

The correct answer is: Biennial

The term that describes plants that produce seeds every two years is "biennial." Biennial plants typically have a two-year life cycle. In the first year, these plants grow leaves, stems, and roots but do not flower or produce seeds. They enter a dormant phase during the winter months and then in the second year, they flower, produce seeds, and die. This life cycle effectively differentiates biennials from annuals, which complete their life cycle in one year, and perennials, which live for more than two years, often flowering and producing seeds multiple times over their life span. The term "seasonal" generally refers to plants that grow or bloom in specific seasons but does not specifically imply a two-year cycle.
