In racemose inflorescence, _________.
Answer: (D) Flowers are borne in an acropetal succession. In a racemose inflorescence the main axis continues to grow and does not terminate in a flower; the flowers are borne laterally in an acropetal succession (oldest at the base, youngest near the growing tip).
- A.The main axis terminates in a flower
- B.Flowers are solitary
- C.The growth is limited
- D.Flowers are borne in an acropetal succession✓
Correct Answer
(D) Flowers are borne in an acropetal succession
Solution & Explanation
In a racemose inflorescence the main axis continues to grow and does not terminate in a flower; the flowers are borne laterally in an acropetal succession (oldest at the base, youngest near the growing tip). Termination of the main axis in a flower and limited growth are features of the cymose type. Hence the correct statement is that flowers are borne in acropetal succession (option 4 = D).
