In a racemose inflorescence, flowers mature in which direction?

• A. Basipetal
• B. Acropetal
• C. Simultaneous
• D. Random

Answer: (B)

Racemose inflorescences show maturation that moves along the axis from base toward the tip, i.e., basipetal development. In these indeterminate inflorescences the main axis keeps growing at the apex, while flowers along the lower part reach maturity first. As you look from bottom to top, you see the oldest flowers blooming near the base and newer ones opening higher up. This sequential pattern distinguishes racemose types from cymose inflorescences, where maturation tends to progress toward the apex (acropetal). Simultaneous blooming or random timing would not describe the orderly, directional sequence seen in racemes.
