A Correct answer
Explanation

A bulb is part modified stem, part modified leaves. The stem portion is compressed and its central terminal bud is surrounded by fleshy modified leaves. Onions, tulips, and daffodils all produce true bulbs. Next time you cut an onion in half longitudinally, look in the centre for the terminal bud.
