In biennials, what forms in Year 1?

• A. Taproot forms (vegetative)
• B. Flowers form
• C. Seeds are produced
• D. Woody stem develops.

Answer: (A)

Biennials have a two-year life cycle. In the first year, the plant focuses on vegetative growth, building up energy reserves and developing structures that will support flowering later. A common way this energy is stored is through a taproot, which acts as a storage organ to fuel the substantial growth and rapid blooming that occur in the second year. That’s why forming a taproot in Year 1 is the typical pattern for biennials. Flowers forming, seeds produced, or a woody stem developing are more characteristic of the second year or of other plant life cycles; many biennials are herbaceous and do not develop woody stems at all during Year 1.
