In racemose inflorescence, ____.

Question

Accepted Answer

D. 1. Recall the two broad categories of **inflorescence**.

Inflorescence is classified based on how flowers are arranged on the floral axis: **racemose** and **cymose**.

2. Understand the growth pattern in **racemose** inflorescence.

Here, the main axis continues to grow indefinitely and does not end in a flower, so the growth is **unlimited**, ruling out options (A) and (C).

3. Understand how flowers are borne along this axis.

Since the main axis keeps growing, the youngest flowers are near the tip and the oldest flowers are near the base, meaning flowers open in an **acropetal succession** (from base towards the apex).

4. Contrast this with cymose inflorescence and eliminate option (B).

In cymose inflorescence the main axis terminates in a flower (limited growth), and "flowers are solitary" describes neither type generally, so option (B) is not correct here.

Hence, the answer is **option D: flowers are borne in an acropetal succession**.
